Crucial Info You Should Know Before Booking Interior Rooms With Carnival Cruises

One of the best ways that you can save money on a cruise is by choosing an Inside or Interior room. They’re not the biggest, but if you don’t plan on spending much time in your room, then does that matter?

Carnival’s cruise ships have many things to see and do on board, so there’s a good chance you won’t use your room for much more than sleeping and getting ready. The cruise line also offers choices for Interior staterooms, and an interesting definition of what an ‘interior’ really means…

Read on to learn everything you need to know about Carnival’s Interior cabins.

Interior Rooms on Cruise Ships

Normally, an Interior stateroom is located on the inside of a cruise ship away from the sides, and has no windows. They’re typically the cheapest and smallest rooms, sleeping anywhere from two to five guests, depending on the cruise line.

The reason I say that they ‘normally’ are on the inside of the ship and don’t have windows is that Carnival does things a little differently. Most of their Interior rooms follow that rule, but they class some rooms that have an ocean view as being Interior, due to the limited view you actually get. More on that later!

The Size of Interior Rooms on a Carnival Cruise

The size of an Interior stateroom on a Carnival cruise ship depends on which ship you’re sailing on, and which category of Interior cabin you choose. You can expect a room that’s between 155 and 185 square feet (14.4 and 17.2 square metres).

The smaller Interior rooms don’t leave you a lot of floor space with a twin or double bed in there, but are some of the cheapest you can book on a modern cruise line.

Bed Types In Carnival’s Interior Rooms

Most Interior staterooms on Carnival cruise ships have two twin beds, which can be converted into a king-size bed on request. Some have one or two Pullman beds as well, to accommodate families – you can get a Carnival cruise interior room for four. Upper/Lower rooms have a single twin bed and either a Pullman or a sofa bed.

Carnival is very much a family cruise line, so there are a lot of choices for Interior rooms if you want to have the kids in the same room as you. Pullman beds aren’t the biggest and won’t be ideal for adults, though you may cope if you want to share a room with friends or teenage kids.

The 9 Types of Interior Rooms on Carnival Ships

When it comes to inside staterooms on Carnival cruise ships, each type has a category code. Although not every ship will have every category, there will still be lots of different accommodation types to consider.

Stateroom Type	Category
Interior Upper/Lower	1A
Porthole	PT
Interior	4A, 4B, 4C, 4D, 4E, 4F, 4G, 4H, 4I
Interior with Picture Window (obstructed views)	4J
Interior with Window (obstructed views)	4K
Premium Interior	4N, 4O
Cloud 9 Interior	4S, 4T
Family Harbor Interior	FA
Havana Interior	HA

Now, let’s take a look at some of these Interior rooms in more detai

Interior Upper/Lower Rooms

An Interior Upper/Lower stateroom (category 1A) is one of the smallest rooms you can book at sea that isn’t a single cabin. It has a single twin bed, and either a Pullman bed or a sofa bed for the second guest. They sleep a maximum of two guests only.

Upper/Lower rooms are interesting. You can’t fit two people in the same bed, so they’re not ideal for couples unless you don’t mind sleeping separately. They’re good for travelling with a friend, as long as one of you doesn’t mind the smaller bed. If you’re a single parent with one child, this room type could be absolutely perfect.

Carnival Cruise Line doesn’t offer single rooms for solo travellers, but the Upper/Lower room is the nearest you’ll get. When the extra bed isn’t made up, it is essentially a single room.

Upper/Lower rooms are small, but again this is a Carnival ship, so you might not care if you’re spending all your time having fun. And the best thing about them is their low cost. You can get a really cheap cruise in one of these rooms – less than $350 per person for a week in the Caribbean.

Some Interior Upper/Lower rooms actually have small porthole windows. On most other cruise ships these would be classed as Ocean View, but Carnival classes any room with small portholes as Interior. So that’s a nice little bonus.

The room shown below is an Interior Upper/Lower, but it has windows and a sofa bed rather than a Pullman bed. The name is quite misleading, both in terms of the ‘Interior’ and the ‘Upper’!

What’s unusual about Interior Upper/Lower rooms is that while some have portholes and some don’t, they all have the same category code of 1A. If you want a room with portholes you can request one, but it’ll depend on availability and your ship.

Interior Upper/Lower rooms are available on all Carnival cruise ships except for the Excel Class ships (Mardi Gras, Carnival Celebration, and Carnival Jubilee) and the Spirit Class ships (Carnival Spirit, Carnival Miracle, Carnival Legend and Carnival Pride).

Porthole Rooms

A Porthole stateroom (category code PT) on a Carnival cruise is still classed as an Interior room, despite having a (limited) view of the ocean. These rooms have twin round windows that are small, but do allow some natural light into the room.

The view you get is pretty limited, especially as the portholes are quite thick and you don’t get a good angle. But it’s something at least. You can at least peek out to see the ocean while you’re sailing and see if it’s sunny or raining.

Otherwise, the room is a fairly standard Interior layout. It has two twin beds that can be converted into a king, and some rooms have extra Pullmans or sofa beds for kids.

Porthole cabins are available on almost all Carnival ships. The exceptions are Spirit Class ships (Carnival Spirit, Carnival Miracle, Carnival Legend and Carnival Pride), and the newer Excel Class.

Obstructed View Rooms

An obstructed view room on a Carnival cruise is one that has something blocking the view from the window or balcony of the room. It may be the lifeboats or, in the case of Interior cabins with a window, the walkway around the edge of the ship.

It feels strange talking about an Interior cabin with an obstructed view, but they do exist on Carnival ships. Most ships in the fleet have an option for an Interior with a Picture Window (Obstructed View – category 4J), which is a half-size window that looks out onto the observation deck. 

So you’ll see the ship’s railing, and maybe some passers-by. Make sure those curtains are closed when you’re getting ready! These rooms are available on all ships except for Spirit Class ships and the Mardi Gras.

In fact, the Mardi Gras doesn’t have any Interior rooms with an obstructed view at all. The Spirit Class ships (Carnival Spirit, Carnival Miracle, Carnival Legend and Carnival Pride) do, but these are called Interior with Window (obstructed view – category 4K). They have floor-to-ceiling windows, so you get a lot more natural light even with the obstruction.

People love Carnival’s 4K staterooms because the odd classification of Interior means that they’re pretty cheap, but with huge windows that let in lots of natural light, even though there is no view due to the lifeboat outside.

Premium Interior Rooms

On Carnival cruises, a Premium Interior (code 4N or 4O) is essentially just a larger version of an Interior room. They’re about the same size as a Balcony cabin, but without the Balcony attached so give you extra floor space compared to a regular Interior. They’re only available on Mardi Gras.

If you aren’t too bothered about having a view, but would like a little more room to move, then a Premium Interior is a good middle ground. You’ll still save money compared to a Balcony, but you’ll feel less cramped.

Cloud 9 Spa Interior Rooms

Guests who book a stay in a Cloud 9 Spa Interior room (category 4S or 4T) enjoy a number of spa-related perks, including priority bookings for the Cloud 9 Spa and access to the Thermal Suites throughout the cruise.

These perks only apply to the first two guests in a Cloud 9 Spa room though. If you’ve booked a room with three adults, someone has to miss out. The Thermal Suites include dry heat chambers, steam chambers and a hydrotherapy pool, which you can use at any time during the cruise.

The priority bookings for the other Cloud 9 Spa services only apply on day one. You can book for any point during the cruise, but from 6pm on embarkation day those slots open up to all guests.

You do get discounts, complimentary yoga or Pilates classes, and some extra spa-branded bathrobes and slippers in your cabin, which are a nice touch. You can’t keep them, though!

Some Cloud 9 Spa Interior rooms do actually have a fairly large window. This overlooks a walkway rather than looking out over the ocean, but if you want some natural light, be sure to look out for these on the deckplans.

Here’s a full list of the perks you get with a Cloud 9 Spa room:

• Easy access to the spa
• Unlimited use of Thermal Suites – Sauna, steam room and hydrotherapy pool
• Complimentary scrub kit to use in Thermal Suites
• Priority spa appointments for reservations made by 6pm on embarkation day
• Discounted spa treatments
• Complimentary Pathway to Yoga or Pathway to Pilates fitness classes
• Complimentary Body Composition Analysis
• Elemis shampoo, shower gel and soap in room
• Spa-branded bathrobes and slippers for use during the cruise
• Relaxing decor in room

Cloud 9 Spa Interior rooms are available on Carnival’s Excel Class, Vista Class, Dream Class and Sunshine Class ships.

Family Harbor Interior Rooms

A Family Harbor Interior room (category code FA) is a fun stateroom for families that is decorated in classic American nautical style. It provides access to the Family Harbor lounge throughout your cruise, which includes a number of perks.

As well as breakfast and daily snacks in the lounge, you’ll also have access to board games, video games and family movies there too. As well as that, kids will eat free at most speciality restaurants on board.

You also get one free evening of Night Owls babysitting at the kids’ club, which is great for when parents want a little bit of quiet time.

Here’s the full list of Family Harbor perks:

• Family Harbor Lounge breakfast in the morning and snacks throughout the day
• A range of board games, video games and movies to enjoy
• Family activities hosted by the youth staff
• Kids eat free in most speciality restaurants
• One free evening of Night Owls babysitting service

Family Harbor Interior cabins can be booked on Mardi Gras, Carnival Celebration, Carnival Jubilee, Carnival Venezia, Carnival Vista, Carnival Horizon and Carnival Panorama.

Havana Interior Rooms

A Havana Interior stateroom (category code HA) is decorated in a more luxurious Old Havana style. These allow guests to access the exclusive Havana Pool area, where you can relax in peace. For that reason, only guests aged 12 and over can stay in a Havana cabin.

They’re not really any more spacious than a standard Interior. You’re just getting a more premium version of the same room, with access to that tranquil pool away from the noisier family pools.

The Havana Pool area has an exclusive swimming pool, two large hot tubs, and a relaxation area with umbrellas, palm trees and comfy seating. There’s also the Havana Bar – this is open to all guests, not just those in Havana rooms. It has lively Latin music and Cuban-inspired coffees and cocktails, making it a really fun place to hang out.

Havana Interior cabins are available on Mardi Gras, Carnival Celebration, Carnival Jubilee, Carnival Venezia, Carnival Vista, Carnival Horizon and Carnival Panorama.

The Pros and Cons of Carnival’s Interior Rooms

Now you know what to expect from all of the different inside rooms on Carnival cruise ships – including those that are labelled as Interior but actually have windows!

I love inside rooms and usually choose one myself. But, before you go ahead and pick one, let’s just make sure that an Interior room is the best room for you.

Here are the pros of booking an Interior cabin on a Carnival ship:

• You’ll save money, which you can use on on-board activities (or another cruise!).
• They’re great if you’re sensitive to light and want a lie-in.
• They can feel quite cosy.

The cons of an Interior cabin:

• You won’t get much floor space.
• If you do choose a Porthole or Window cabin, the view isn’t great anyway.
• You might miss natural light if you choose a true Interior cabin.

Deciding Whether To Book An Interior Room on a Carnival Cruise

There’s no right or wrong answer on which is the best room on a Carnival cruise, because it depends on the individual. You might feel claustrophobic in an Interior room, and if that’s the case then you definitely shouldn’t book one! It’s not worth making yourself uncomfortable just to save some money.

If you aren’t going to feel cramped, or plan on barely spending any awake time in your cabin at all, then an Interior Room could be a really good option. They can be pretty cheap, depending on the itinerary and ship, and because they’re a little cosier you might even sleep better.

However, don’t forget about the lack of natural light, which could be a dealbreaker. If you think that natural light is important in your bedroom, look out for Interior rooms with portholes or obstructed views, or consider paying a little more for an Ocean View stateroom.

If space is important to you, and you’ve got the budget to spare, then a Balcony could be a better option than a Carnival cruise interior room. They’re the best choice if you are prone to feeling cramped, because even a small balcony in the fresh air can feel very open and relaxing.

My Recommendations for Booking Carnival’s Interior Rooms

The number one reason that people choose to book an Interior cabin on a cruise is to save money. For that reason, I don’t think there’s such a thing as a ‘bad’ Interior cabin on a Carnival cruise. 

Some of them are definitely more cramped than others, especially the Upper/Lower ones. But the cost savings could make the difference to your overall cruise holiday.

I would say that a Porthole cabin isn’t worth paying any extra for, compared to a standard Interior. Yes, you get a tiny bit of natural light, but the thickness of the walls means that the amount is limited, as is the view.

If you’ve got the money, I suggest looking at the Family Harbor, Cloud 9 or Havana Interiors. The Family Harbor is one of the best Carnival cruise rooms. It’s a great budget choice when cruising with kids, and the extra activities help to keep them entertained during quieter moments.
