A guarantee cabin can look like a bit of a steal when you’re pricing up a cruise. Same ship, same itinerary, same holiday. Just cheaper if you let the cruise line pick your room.
Sounds great, right? Well…
The catch is simple enough. You’ve got to be fine with whatever you’re given – not the cabin you’re picturing, not the one someone says you might get, but the one you’d end up with if luck isn’t on your side.
That’s where it falls apart for some people. Here’s what tends to trip people up.
Guarantee Cabins Explained
Just in case you’re new to cruising, let’s quickly go over what we mean by a guarantee cabin. Essentially, they’re exactly what they sound like – you’re guaranteed a cabin in a certain category, but not a specific room.
So instead of choosing your exact cabin number, you’ll book something like an inside, ocean view or balcony guarantee. The cruise line then assigns your cabin for you, sometimes weeks before sailing, sometimes just days before – and occasionally even at the port.
The only thing you’re promised is the category, or better. That means you won’t be downgraded, but you also won’t have any control over where your cabin is located on the ship.
That’s why guarantee cabins are cheaper – you’re trading control for a lower price, and leaving the final decision in the cruise line’s hands.
And here’s why that might be a bad thing…
1. You Can’t Choose Your Cabin Location
You’re picking a category, not a cabin.
So yes, you can choose inside, ocean view or balcony. But where that cabin actually is? That’s completely out of your hands.
Cruise lines don’t admit this, but it’s hardly a secret: not every location on a ship is equal, and there are some that can sometimes be downright problematic.
You could land somewhere great. Or you could be at the very front, the very back, stuck on a low deck, or miles from anything useful.
If you’ve never really cared about location before, it might not bother you. But if you’ve ever looked at a deck plan and thought “I’d rather not be there”, it probably will. And yet by choosing a guarantee cabin,
2. You Could End Up Somewhere Noisy
Some cabins get booked last for a reason.
Under the pool deck is a classic one. Early morning scraping of loungers, people dragging chairs around. So much for that lie-in. Cabins near theatres or night venues can have the opposite problem – noise when you’re trying to sleep at night.
Then there are the less obvious ones. Crew doors opening and closing, service areas, or that heavy, echoing thud when the ship docks if you’re too far forward.
You can’t avoid every bit of noise on a ship, but choosing your own cabin at least gives you a chance to dodge the obvious hotspots.
3. Not Ideal If You Get Seasick
If you already know you get motion sickness, this is where a guarantee can feel like a gamble in the worst way.
Most people find midship, lower down, to be the most stable part of the ship. Head too far forward or aft and you’ll feel more movement, especially if the weather turns.
It doesn’t ruin every trip, but it can make a difference day to day. And if you’ve had a rough crossing before, you’ll know exactly what that feels like.
4. An ‘Upgrade’ Might Not Feel Like One
Yes, upgrades do happen on occasion when you book a guarantee cabin. Just not always in the way people imagine.
You might move up a category without it actually improving your experience. A higher grade cabin on paper could still have an obstructed view, an awkward layout, or be in a spot you wouldn’t have chosen.
Connecting cabins are another one. Handy for families, less so if you weren’t planning on hearing your neighbours.
It’s easy to get caught up in the idea of getting something “better”, but better doesn’t always mean better for you.
5. You Might Not Know Your Cabin Until Late
Sometimes you’ll get your cabin assignment fairly early. Other times it drags on until a few days before sailing. Occasionally, people don’t find out until they arrive at the port.
That uncertainty doesn’t bother everyone. Some people quite like it.
But if you’re the kind of person who checks deck plans, looks up what’s above and below, or just likes having everything sorted in advance, it can feel a bit unfinished.
Royal Caribbean have introduced a new Early Assign option on some cruises – with a $30 fee. So you can get around the issue of finding out your cabin too late, but it’ll cost you.

6. It’s Trickier When You’re Travelling With Others
Once other people are involved, and you’re booking more than one cabin, location starts to matter a lot more.
You might want cabins next to each other, opposite each other, or at least on the same deck. With a guarantee, you’re leaving that completely open. Even within the same booking!
It can work out fine. It can also leave you spread across the ship. For families with younger kids, that’s often enough to rule it out straight away.
I once booked three guarantee cabins on a Royal Caribbean cruise. I could see that the room type we wanted only existed on Deck 3, so I thought that’s fine, as at least the cabins will all be on the same deck. What I didn’t consider was that deck 3 also had the ice rink and we had cabins on either side of it.
The only way to get to each other’s rooms was to go up to deck 4, along and back down!
7. The Savings Aren’t Always That Big
The price difference is where this either makes sense or doesn’t. If you’re saving a decent chunk, it’s easier to accept the trade-off. If the gap is small, it’s a totally different story!
That’s usually when people start second-guessing it. Especially if they end up in a cabin they wouldn’t have picked for themselves.
A quick gut check helps here. If you’d be annoyed getting the worst cabin in that category, the saving probably isn’t enough.
In some cases, I have even seen the guarantee cabin cost more than the ‘pick your room’ option. I’ve no idea why!

8. The Fare Can Be More Restrictive
A lot of the time, when you’re considering a guarantee cabin, it’s not just the cabin itself that you’re giving up control over.
Guarantee fares often come with tighter terms – less flexibility if you need to change anything, sometimes fewer perks, sometimes stricter deposit conditions.
It doesn’t always jump out when you’re booking, but it can matter later.
Make sure you take your time with the booking and you fully understand what the rules are with the fare you choose, or you could leave yourself in bother if you want to make changes later.
9. You’re Often Getting Leftover Cabins
Here’s the thing that you need to realise with guarantee cabins – most of the time, these are the cabins that weren’t snapped up earlier. The ‘unwanted’ cabins by those people who wanted to pay more to choose their location.
That doesn’t automatically mean they’re bad. Some are absolutely fine. Occasionally you’ll get a really good one through a late cancellation, which is a nice little win!
But generally, if a cabin sat un-booked for longer, there’s usually a reason. Location, layout, view – something about it wasn’t as appealing to the people who didn’t mind spending a bit more.
10. First-Time Cruisers Are Usually Better Off Choosing
On a first cruise, there’s already a lot that feels new. The ship layout, how everything works, what you actually use during the day.
So adding uncertainty about your cabin into that mix doesn’t always help.
Once you’ve done a cruise or two, you’ll have a much clearer idea of what matters to you. At that point, taking a punt on a guarantee feels a lot more informed.
But I would definitely say that choosing your specific cabin is a good idea for your first one.
When A Guarantee Cabin Does Make Sense
For all that, there are plenty of situations where booking a guarantee cabin is the smart move.
Short cruises are probably the easiest example. If you’re only onboard for a few nights, you’re not exactly settling in. You’re out, you’re exploring, you’re making the most of the ship. The cabin becomes somewhere to sleep and get changed, and not much more than that.
It also starts to make a lot more sense when the price gap is properly noticeable. Not £50 or £100 – the kind of saving that actually changes the feel of the booking. Maybe it means upgrading your drinks package, booking more excursions, or just making the overall cost feel more comfortable.
There’s also a type of cruiser it naturally suits.
If you’ve cruised before and already know you’re not that bothered about location, you’re in a much better position to take the gamble. Some people realise pretty quickly that they don’t spend enough time in the cabin for it to matter. Once you know that about yourself, a guarantee fare becomes a lot easier to justify.
Last-minute bookings are another good fit. When there are fewer cabins left overall, the gap between “guarantee” and “choose your exact cabin” tends to shrink anyway. At that point, you’re often just taking whatever’s available, so letting the cruise line assign it doesn’t feel like much of a sacrifice.
It can also work well if you’re booking a lower cabin category on purpose. For example, if you’re happy with an inside cabin and not emotionally invested in where it is, there’s less to lose. You’re not worrying about balcony views or specific positions – it’s already a more functional choice.
And then there are people who just enjoy the unknown a bit.
For them, the assignment isn’t a source of stress, it’s part of the experience. Checking the app, waiting for the cabin number to appear, seeing where they’ve ended up – it adds a bit of anticipation rather than taking anything away.
Guarantee cabins work best when you’re flexible, when the saving actually matters, and when the cabin itself isn’t a big part of how you measure the trip. If those boxes are ticked, it can feel less like a gamble and more like an easy win.
Final Word
Guarantee cabins aren’t a bad idea, they’re just not as straightforward as they look.
For some people, they work out perfectly. For others, they’re one of those decisions that feels clever at the time and slightly annoying later.
If you’d be content with the worst cabin in the category, it’s a reasonable gamble. If you wouldn’t, you’re probably better off choosing your cabin and not thinking about it again.
