Find the room that sleeps like you do.

How well a specific room fits the way you sail. Pick your ship and answer a few taps, and it ranks every room we hold for her: motion, sleep, the view, room to spread out and, where we have it, the walk to the elevators. It isn't a rating of how nice a room is. A beautiful suite can be the wrong room for a light sleeper under the pool deck, and a plain interior can be the right one.

Yes. Choose Check my cabin and type the number on your booking. You get its Fit, where it ranks among the same kind of room on that ship, and a plain verdict: keep it, a good room worth asking about a couple of others, or worth asking about a move. If a better room sits in your same category, it says so, because a move inside your category usually costs nothing.

Sometimes the data can't tell two rooms apart. On a ship where every standard balcony is listed at the same size and there's no room-by-room noise survey, a light sleeper and a seasick traveler really are best served by the same low, midship room. Where on the ship you want to be (low, high, forward, aft or midship) is the biggest lever after room type. Under the ship picker, Cabin Fit shows what it can and can't judge for that ship.

Each line's own published deck plans and category specifications. Every room's deck, how far forward or aft it sits, its view, size, occupancy and category are read from them. On some ships we also hold a room-by-room noise survey and elevator walking times. Nothing is crowdsourced or taken from reviews, and where a size is the category's figure rather than a measurement of your exact room, it's treated that way.

If a ship's data can't judge something at all, that question is switched off for every room on her, and the page tells you. If one room is missing a fact its neighbors have, it's held at the ship's average for that fact, so it neither gains nor loses, and its confidence line shows how much of its score rests on its own record.

From two things the deck plan knows exactly: how far forward or aft the room sits, and how high it is. Midship and low is steadiest. The bow pitches most in a head sea, and the far stern sits over the propulsion, which is scored separately as vibration. It's a tendency of the position, not a forecast of your sailing's weather.

From position, and it's labelled that way. The far stern sits over the propulsion, the lowest rooms at the very front sit near the bow thrusters and the anchor, and the top cabin deck sits under the open decks, where loungers get moved early. It counts for less than a real survey, and it never claims a room was checked.

Occupancy comes from the deck plan, so it's a fact, not a preference. If a room sleeps two and you have four, there's no Fit to show at any number. Rooms whose category allows your party but whose exact bed count we don't hold carry a note to confirm it before you book.

Cabin Fit reads deck plans, never live inventory, so it shows the rooms that fit you, not the ones that are free on your date. Send us the shortlist with your sailing date and we'll tell you what's open and which category gets you there for the least.
