Celebrity Millennium Cabins To Avoid

Not all cabins on the Celebrity Millennium offer the same experience – and some can seriously detract from your cruise. From noisy hotspots to obstructed views, a few staterooms could be more trouble than they’re worth.

Even experienced cruisers can get caught off guard by poor cabin placement or misleading descriptions. A great deal isn’t always a good decision.

Before you book, here are the specific cabins you’ll want to avoid – and why choosing the wrong one could cost you.

Celebrity Millennium Cabin Guide

Before we get right into the detail of the cabins you’ll want to avoid, it’s best to look at the bigger picture of all the cabin options available to you on Celebrity Millennium.

There are six main ‘types’ of cabin you can choose from:

Accommodation	Sleeps	Size (incl. veranda where applicable)
Inside	2 to 4	170 sq. ft.
Ocean View	2 to 4	170 to 242 sq. ft.
Veranda	2 to 5	213 to 538 sq. ft.
Concierge Class Veranda	2 to 3	251 to 275 sq. ft.
AquaClass Veranda	2	243 sq. ft.
Retreat Suites	2 to 4	311 to 2,530 sq. ft.

In terms of your cruise cost, choosing between these cabin types is going to play a major role in your budget. An Inside Stateroom could cost a fraction of a Suite, for example.

Of course, the cheapest fare isn’t always the best option either, especially if you end up booking a cabin that just isn’t a good fit for your needs.

There’s a lot to think about when choosing your cabin, and I’m not just talking about on Celebrity Millennium – this applies to any ship.

So to help, I’d recommend you grab a copy of my cabin checklist. This can be applied to any ship to help you narrow down your decision every time you book a cruise.

Inside Cabins

Your Inside Staterooms on Celebrity Millennium are your entry-level options. When you see a cruise fare advertised on a website, most of the time you’re looking at the price for the Inside – anything above this grade will cost extra.

They’re not just good if you’re on a budget though. Some people prefer them because they’re so dark – they’re fantastic if you want a deep sleep.

And there are options available across many decks, not just the very bottom ones – so you shouldn’t worry about feeling buried at the bottom of the ship if you’d rather be nearer the pool.

Inside Cabin Grades

Grade	Sleeps	Size (sq ft)
I1 – Prime Inside	2 to 4	170
I2 – Inside	2 to 4	170

There are only two categories of Inside, and in terms of size they’re identical. The difference between a regular Inside and a Prime Inside is purely location.

Regular Insides are on decks 2 and 3, while the Prime Insides are higher, on decks 6-9 and Deck 11.

Most cruisers prefer to be higher up on a cruise ship because you’re closer to the pool deck, but there are features on Deck 4 like the Theatre, the Martini Bar and the main dining restaurants that you might prefer to be nearer to, also.

Oceanview Cabins

Oceanview Staterooms on Celebrity Millennium are the next step up from the Inside cabins. They come with a window that gives you natural light and a view of the sea, though the size and placement of that window can vary.

They’re a solid choice if you want a more open feel without the higher cost of a balcony. And if you’re someone who struggles with seasickness (more on that in a bit), then you might prefer a lower-deck Oceanview so you’ve a view of the horizon. It helps.

You’ll find Oceanview cabins spread across several decks, giving you a decent amount of choice when it comes to location.

Oceanview Cabin Grades

Grade	Type	Sleeps	Size (sq ft)
DO	Deluxe Ocean View	2	242
O1	Prime Ocean View	2 to 4	170
O2	Ocean View	2 to 4	170

There are three types of Ocean View cabin on Celebrity Millennium. Again, there are regular Ocean View and Prime Ocean View which are the same size, but in different locations.

Regular Ocean View Staterooms are on decks 2 and 3, while the Prime options are also on those decks (but closer to mid-ship), as well as on decks 6 and 7 (in a forward position).

Deluxe Ocean View Staterooms are larger. On decks 6 and 7 they are right at the front of the ship, with forward-facing windows. An example is here, with cabins 7000 to 7003:

On decks 8 and 9 they are still near the front, but they are simply longer versions of the Prime Ocean View Staterooms, with port- and starboard-facing windows. Cabins 8002 and 8003 are two examples:

Veranda Cabins

Veranda Staterooms on Celebrity Millennium offer your first real taste of private outdoor space. These cabins come with a balcony, giving you fresh air, sea views, and a place to relax without leaving your room.

They’re popular with cruisers who like to enjoy a quiet morning coffee outside or watch the sailaway in peace. The extra space makes them feel noticeably less confined than Oceanview or Inside cabins.

Verandas are available on multiple decks, but not all are equal – some have smaller balconies, obstructed views, or are in noisier spots.

Veranda Cabin Grades

Grade	Type	Sleeps	Size incl. veranda (sq. ft.)
UV	Ultra Deluxe Veranda	2 to 5	538
SV	Sunset Veranda	2	251
DV	Deluxe Veranda	2 to 3	251
V1	Prime Veranda	2 to 4	213
V2	Veranda	2 to 4	213
V3	Veranda (Partial View)	2 to 4	213

There are no shortage of Veranda cabin types!

V1, V2 and V3 are pretty self-explanatory by now. V1 are in a better location (mid-ship on Deck 7 or forward on Deck 9), while V2 are available on decks 6-8 and 10.

V3 are all in forward locations and have a partially restricted view caused by the overhang of the ship and its superstructure. On decks 9 it’s more prominent, while on decks 7 and 8 it’s vertical beams blocking the view slightly.

Deluxe Veranda Staterooms are larger rooms, and Sunset Veranda rooms have an aft view for you to enjoy – many people believe that the aft is the best view on the ship as you can enjoy watching the ship’s wake.

The Ultra Deluxe Veranda Staterooms are huge by comparison to others, with a balcony alone that’s around the same size as a regular Veranda Stateroom. These can also sleep up to 5 guests and so are a good option for families.

Concierge Class Cabins

Concierge Class Staterooms on Celebrity Millennium are a step up from standard Veranda cabins, with the same private balcony and layout – but paired with extra perks that focus on comfort and convenience.

They’re ideal if you like a little more personal service without going all the way to a suite. The extras aren’t flashy, but they do add up to a noticeably smoother experience, especially on busy embarkation and port days.

The key Concierge Class benefits include:

• Priority check-in and priority tendering at ports
• Access to a private embarkation day lunch
• Daily canapés delivered to your cabin
• Dedicated Concierge desk for help with bookings and issues
• Upgraded toiletries, pillow menu, and premium linens

Grade	Type	Sleeps	Size incl. veranda (sq. ft.)
UC	Ultra Deluxe Concierge	2	275
C1	Prime Concierge	2 to 4	251
C2	Concierge	2 to 4	251

As per the other classes, your C2 options are regular Concierge Class Staterooms while the C1s are Prime options in a better location. UC are Ultra Deluxe Concierge Class, with extra space and being situated right amongst the suites on the ship.

AquaClass Cabins

AquaClass Staterooms on Celebrity Millennium are veranda cabins with a wellness-focused upgrade. You get all the essentials of a standard Veranda, but with added spa access, healthier dining, and a few in-room extras designed to help you unwind.

They’re a strong choice if you like quiet spaces, lighter meals, and the idea of turning your cruise into a mini wellness retreat. You don’t need to book a suite to get that spa-lounge feel.

Here’s what you get with AquaClass on Celebrity Millennium:

• Unlimited access to the Persian Garden thermal suite
• Exclusive dining at Blu, a clean and spa-inspired restaurant
• Massaging showerhead, upgraded toiletries, and aromatherapy options
• Daily bottled water, yoga mats, and a pillow menu
• Priority check-in and a dedicated spa concierge

Grade	Type	Sleeps	Size incl. veranda (sq. ft.)
A1	Prime AquaClass	2	251
A2	AquaClass	2	251

The Retreat Suites

The Retreat Suites on Celebrity Millennium are the ship’s most exclusive accommodations, offering spacious layouts, premium amenities, and access to private areas that regular guests can’t enter. You still get a veranda, but everything else is a serious step above.

They’re the right pick if you want more privacy, top-tier service, and perks that take care of almost everything for you – from dining to drinks to disembarkation. It’s a quieter, more personal cruise experience from start to finish.

Here’s what you get with The Retreat:

• Access to Luminae, a private restaurant with menus by chef Daniel Boulud
• A dedicated Retreat Lounge and exclusive Sundeck with cabanas and poolside service
• Full butler service, concierge team, and priority everything
• Unlimited premium drinks, premium WiFi, and daily in-suite canapés
• Luxury extras like upgraded bedding, robes, a pillow menu, and a welcome bottle of sparkling wine

Suite	Code	Sleeps	Size (incl. veranda, sq. ft.)
Sky Suite	S1, AS	2 to 3	311
Celebrity Suite	CS	2 to 3	587
Royal Suite	RS	4	757
Penthouse Suite	PS	3	2,530

The Sky Suites are the smallest suites on the ship, while the largest are the stunning Penthouse options which take up entire aft corners.

One category worth mentioning is the AS – these are classed as Aqua Sky Suites. They’re the same size as other Sky Suites but they combine some of the wellness perks of the AquaClass with your regular Suite perks too.

Special Cabins on Celebrity Millennium

There are a couple of special cabin types worth mentioning on the ship – it’s best to only book these if you need them.

Connecting Cabins

Celebrity Millennium offers a number of connecting cabins, ideal if you’re traveling with family or a group and want to stay close while still having some separation.

These staterooms are joined by an internal door, so you can move freely between them without going out into the hallway.

You’ll find connecting options across several categories, including Inside, Oceanview, Veranda, and even Concierge Class. Look for a line connecting two rooms on the deck plans for the ship.

Accessible Cabins

There are a limited number of accessible staterooms on Celebrity Millennium, thoughtfully designed for wheelchair users and guests with mobility needs.

These cabins are larger than standard ones in the same category and feature wider doorways, roll-in showers, grab bars, lowered sinks, and ramped bathroom thresholds.

You’ll find accessible options in Inside, Oceanview, Veranda, Concierge, AquaClass, and even The Retreat categories (Sky Suites only).

They’re best reserved for guests who genuinely need the space and features, as availability is limited and demand is high.

Celebrity Millennium Cabins to Avoid

Here’s a look at the cabins that you might want to avoid when booking your Celebrity Millennium cruise.

1. Aqua Sky Suites With Exposed Balconies

6131 and 6132

There are two Aqua Sky Suites located on Deck 6 that have larger balconies than any other in the category – but it comes with a drawback.

These cabins are at at angle as the after of the ship expands out, and so the balconies are at a 45° as well.

The problem with this is that it means several cabins along the ship have a view into at least half of your balcony, especially the adjacent Aqua Sky Suites – so your privacy is extremely limited.

It only really impacts these two suites. On the higher decks, the ship doesn’t widen out quite so dramatically and so the balconies are a little more protected.

It’s one for you to weigh up – would you rather have the extra space, despite losing some of your privacy?

2. Inside Cabins on Deck 9

9087, 9091, 9103, 9107, 9115, 9119

Whenever I write a ‘Cabins to Avoid’ guide, a recurring suggestion is to avoid the cabins directly underneath the pool deck. And these Inside Cabins are exactly that – directly under the space where the pool is situated.

This means you’re more likely to hear noise, especially early in the morning when people are dragging sunbeds around on the wooden decking. That sound can really carry into the room.

9087 and 9091 might not be too bad because they’re directly under the pool itself, but the others are underneath prime seating areas.

If you like a lie-in, then I’d avoid these.

3. AquaClass Cabins on Deck 9

The AquaClass Cabins on Deck 9 suffer from the same issues as those Inside Cabins I just mentioned – they’re directly underneath the pool deck and so could suffer from noise, especially as it’s one of the more popular areas of the ship during daytime hours.

There’s also an overhang that doesn’t technically count as an obstruction but could limit how much sunbathing time you get on the balcony.

One other thing to consider is that some reviewers say that the AquaClass staterooms feel a bit worn. The ship did undergo a routine drydock in 2024 but the last big renovation took place in 2019.

Considering the cost of these cabins, maybe avoid them if you’re worried about the noise or the overhang blocking the sun.

4. Worst Cabins If You Get Seasick

Deck 10 Verandas (1000 to 1024), Deck 11 Prime Inside & Prime AquaClass (1100 to 1141)

If you’re prone to seasickness, then your choice of cabin location is really important – and these ones are the riskiest.

The V2 Veranda staterooms at the very front of Deck 10 (cabins 1000 to 1024), and the Prime Inside and Prime AquaClass staterooms at the aft of Deck 11 (1100 to 1141), are the highest cabins on the ship.

That combination – forward/aft and high up – is where the ship’s motion is most noticeable. You’ll feel more movement here during rougher seas, especially if you’re sailing in less calm waters or during shoulder seasons.

If you’re worried at all about getting queasy, then these cabins are best avoided. You’re better off picking an Ocean View or Veranda Stateroom on a lower deck (being able to see the horizon can help) and ideally somewhere midship, where movement is minimal.

5. Concierge and AquaClass Cabins If You Won’t Take Advantage

Concierge Class and AquaClass cabins offer some nice perks, sure – but they do come at a price, and they’re not always worth it.

These staterooms are generally more expensive than standard Veranda cabins, but the upgrades aren’t necessarily about a better cabin – they’re mostly about the added extras like exclusive dining (Blu for AquaClass), priority boarding, or expanded room service menus.

And while some locations for these rooms might be slightly more desirable, the actual views and room sizes are pretty similar to regular Verandas.

So unless you know for sure that you’ll use the extras – like daily spa access, or attending the Concierge-hosted events – you might be better off saving your money and just booking a Veranda Stateroom instead.

6. Deck 2 Cabins Due To Engine Noise

Some guests have reported that cabins on Deck 2 can be noisier than others – mainly because of their proximity to the ship’s engines and lower mechanical areas.

It’s not something that everyone will notice, and you might sleep right through it.

But light sleepers, or those who are sensitive to low-frequency noise or vibration, could find the engine hum and occasional vibrations a bit intrusive, especially at night or early in the morning when the ship is docking.

Remember that it’s an older ship and so vibration is more likely to be noticeable than on newer ones.

There aren’t a huge number of cabins down here, but if you’re trying to choose between a Deck 2 Ocean View and one on Deck 3 or 4, it might be worth choosing the one slightly higher up, just for peace of mind – quite literally.

7. Obstructed View Cabins

There are several cabins on the ship where you’ll have an obstructed view, and a lot of people might prefer to avoid these if your priority is soaking up those sunsets from your own private balcony space.

The obstructions can vary from a 5% obstruction all the way up to a 50% one, although most obstructed rooms have either a 10% or a 25% obstruction.

Usefully, Celebrity Cruises has produced a list of all the obstructions:

Category	Stateroom	Obstruction		Category	Stateroom	Obstruction
A1	9047	25%		V3	8007	5%
A1	9045	25%		V3	8006	5%
A1	9042	25%		V3	7021	20%
A1	9040	25%		V3	7019	20%
V3	9009	25%		V3	7018	20%
V3	9008	25%		V3	7017	20%
V3	9005	50%		V3	7016	20%
V3	9004	50%		V3	7014	20%
C1	8050	25%		DV	6025	10%
C1	8049	25%		DV	6023	10%
C1	8048	25%		DV	6021	10%
C1	8047	25%		DV	6020	10%
V3	8011	25%		DV	6018	10%
V3	8010	25%		DV	6016	10%

And not only that, but you can also see images of what most of those obstructions look like if you check out this document.

You’ll notice, though, that a lot of those cabins aren’t classified as being obstructed view according to the cabin categories. There are a lot of V3, sure, but also some A1 Prime AquaClass, C1 Prime Concierge Class, and DV Deluxe Veranda.

So be extra careful when booking those categories!

8. Deck 3 Cabins Due To Deck 4 Noise

This one’s definitely more of a soft warning because there aren’t many complaints about it at all – there’s a good chance you can book a Deck 3 cabin and be absolutely fine.

But I’d rather mention it in a case of being abundantly cautious, than not.

Deck 3 has a number of Inside and Ocean View Cabins situated below the busy Deck 4. Deck 4 is home to a number of features including the main dining room, the theatre, the casino and several bar/lounge spaces.

But the noisiest of those – the theatre and the restaurant – aren’t directly above any cabins. And the lounge and bar spaces that are above the cabins on Deck 3 aren’t going to be playing loud music until late in the night.

If you’re really sensitive to sound then perhaps you’ll hear noise from guests above later at night, but you’re probably OK in these cabins.

9. Inside or Ocean View Cabins for 4 Guests

There are several cabins on Celebrity Millennium that can sleep up to four guests. This is denoted on the deck plans either with a circle (showing two upper beds), or a square and a triangle together, which means a single sofa bed and a single upper bed.

But some of these cabins with two upper beds are Insides or Ocean View Staterooms and I just don’t think they’re big enough to be comfortable.

If you’re travelling as a couple then they’re fine, but with the beds down you really have limited space – you’re not just worrying about where to put your feet, but also making sure you don’t bang your head.

Bigger travelling parties should absolutely book a Veranda if they can.

The Best Cabins on Celebrity Millennium

There are a couple of real standout options on Celebrity Millennium that are always worth considering – budget depending.

1. Ultra Deluxe Veranda Staterooms for Families

If you’re cruising as a family, these are absolute gems. The Ultra Deluxe Veranda Staterooms sleep up to five guests, which is a rare find on most cruise ships where the maximum is usually four.

Not only do they offer that extra bed space, but they’re also significantly more spacious than a standard Veranda, giving everyone a little more room to spread out.

Located right at the aft of the ship, you’ll also get those wake views that many guests consider the best on board.

They combine comfort, space, and a fantastic location – a great choice for larger families who still want a balcony and a bit of luxury.

2. Sunset Veranda Staterooms

The Sunset Veranda Staterooms are a fan favourite – and for good reason. You’ll get a slightly larger balcony than standard Veranda cabins, which means more space for loungers and a better angle for those evening drinks as the sun goes down.

Being located right at the aft of the ship, you’ll enjoy uninterrupted panoramic views over the ship’s wake – often considered one of the most peaceful and photogenic spots on board.

This video shows a Sunset Veranda on a sister ship:

And because these cabins are tucked away at the back, the location tends to be quieter, with less foot traffic passing your door. It’s a perfect blend of scenery and serenity.

3. Royal Suites and Penthouse Suites

If you want the best of the best on Celebrity Millennium, the Royal Suites and especially the Penthouse Suites are where you’ll find it.

These are the largest accommodations on the ship, with the Penthouse offering incredible amounts of space – I’m talking full living and dining areas, a huge balcony, and even a private hot tub.

Both suite types come with access to The Retreat, Celebrity’s exclusive suite-only area, which includes a private lounge, sundeck, and restaurant. The service here is top-tier, with butlers, priority everything, and a level of personal attention that makes you feel like a VIP from the moment you step on board.

If your budget allows, these suites turn your cruise into a true luxury experience.

Final Word

Celebrity Millennium may be one of the older ships in the fleet, but don’t let her age fool you – she still offers a refined, premium cruising experience with elegant spaces, personalised service, and a classy, quieter vibe that many guests absolutely love.

That said, not all cabins are created equal. Depending on what matters most to you – whether it’s extra space, reduced motion, a quiet location, or the best possible view – some rooms are going to suit your needs far better than others.

Much of the information in this guide has come from trawling through reviews, cruise forums, and real guest feedback – the kind of insight you only get from people who’ve been there, stayed there.

And if you’re still not sure about a particular cabin, those same places (especially Facebook groups or Cruise Critic forums) are great for asking questions.

Someone out there has likely stayed in the exact cabin you’re considering – and they’ll probably be happy to give their honest thoughts.

One final tip: before you book, take a moment to study the Celebrity Millennium deck plans.

Just a quick check of what’s directly above, below, or beside your chosen stateroom can make a huge difference – it might be the key to avoiding late-night noise or securing that peaceful spot for a perfect night’s sleep.
