Not "is it a nice room" — is it right for you. Enter your ship and cabin number and we score that exact room against the way you sleep, how motion treats you and what you actually want to be near — from the line's own deck plans. Then we rank it against every other cabin on your deck.
Cabin Fit answers one question: how well does this exact room suit the way you sail. Here is the whole method, with nothing hidden behind the number.
Deck, fore-aft position, view class, confirmed occupancy, and what sits above, below and beside the room — all read from the line's published deck plans and category specs at build time. Walk times to the lifts, the pool, the theater and the kids' clubs are computed from that geometry, not estimated from reviews.
Noise carries the most weight by default, then motion, then view. Tell us you are a light sleeper and noise counts for more; tell us motion really bothers you and the fore-aft position starts to dominate. Pick up to three priorities and those categories are lifted further. Every weight is printed on the breakdown, as a percentage of your result.
Occupancy is a fact: a cabin that cannot sleep your party is blocked outright rather than quietly marked down. And when a category you said matters most scores badly, it caps the overall fit — because a great average is no comfort if the one thing you cared about is the thing that is wrong.
Every fact carries a provenance tier. A figure that is a category median rather than a measurement of your exact room is labelled as an estimate on the card, and the confidence line under your score tells you how much of it rests on derived geometry rather than published detail.
If the categories you weighted most are exactly the ones we lack sourced data for on that cabin, the tool shows no score at all and names what is missing. A confident-looking number built on a gap would be worse than a blank.
Once your cabin is scored, every other cabin on the same deck is scored the same way against the same answers — so you can see whether yours is genuinely good or merely acceptable, and exactly which rooms beat it and by how much. Cabins, not availability: what is bookable on your sailing is a question for us.
Motion here is a property of where the cabin sits, not a weather forecast. A midship cabin in a January North Atlantic crossing will move more than a forward cabin in a flat Caribbean week. The position is the part we can know honestly; the sea is not.
The deck ranking compares cabins, not inventory. A room scoring eight points higher than yours may have been sold months ago. Ask us and we will check what is actually free on your date — and whether the move is worth the fare difference.
38 ships across 3 lines are sourced to this standard today — 30 from Royal Caribbean, 4 from Virgin Voyages, 4 from Disney Cruise Line. A real cabin whose position we cannot yet place is told exactly that — never redirected to a guess — and other lines are added only when their deck plans are read to the same depth.
How well one specific cabin — the room number on your booking — matches the way you personally sail. It reads that cabin's real position on the deck plan and scores seven things against your answers: noise, motion, view, the walk to the pool and theater, the walk to a lift, kids' club convenience and the room itself. It is not a rating of how nice the cabin is. A beautiful suite can be a poor fit for a light sleeper directly under the nightclub, and a plain interior can be an excellent one.
each line's own published deck plans and category specifications. Every cabin's deck, fore-aft position, view class, occupancy and its neighbours above, below and beside it are read from those plans at build time. Walk times are computed from that geometry. Nothing here is crowdsourced, scraped from reviews, or guessed — and where a figure is a category median rather than a measurement of your exact room, the page says so on the card.
Because a confident-looking number built on missing evidence is worse than no number. If the categories you told us matter most are exactly the ones we lack sourced data for on that cabin, Cabin Fit shows nothing and says which piece is missing. It is the same principle as the rest of the site: we would rather tell you what we don't know.
Occupancy is a hard fact from the deck plan, not a preference. If a cabin's confirmed capacity is two and you have four people, there is no score to show — it isn't a fit at any number. That is a block, not a low score, and the page says so plainly instead of quietly marking the cabin down.
From two things the deck plan knows exactly: how far fore or aft the cabin sits, and how high it is above the waterline. Midship and low is steadiest; the bow pitches most in a head sea, and the stern sits over the pods. The diagram on your verdict shows precisely where your cabin falls on both axes — that picture is the score, drawn. Motion is a physical tendency of the position, not a forecast of your sailing's weather.
Every other cabin on your deck, scored with the same engine against the same answers, so you can see whether yours is a good room on that deck or a compromise. It is a comparison of cabins, not of availability — we cannot see what is left for your sailing. If a better-scoring room appears, ask us and we will check whether it is actually bookable.
Yes, and that is the point. The same cabin scores differently for a light sleeper than for a heavy one, and differently again for a family who needs the kids' club than for a couple who wants a view. The cabin's facts never move; the weights do. Tap a different answer and watch the number and the breakdown change.
38 ships and 56,077 sourced cabins across 3 cruise lines — 30 from Royal Caribbean, 4 from Virgin Voyages, 4 from Disney Cruise Line. That is Royal Caribbean's Icon, Oasis, Quantum, Freedom, Voyager, Radiance and Vision classes, Virgin's Lady class, and Disney's Magic and Dream classes. Cabin Fit only covers cabins whose position we hold from a published deck plan; a real cabin we cannot yet place gets an honest 'it exists, we don't know where' message rather than an invented answer. Other lines follow as their deck plans are sourced to the same standard.
Only in this browser, and only so the site's other fit tools can pick up where you left off. Nothing is sent anywhere, there is no account, and the whole tool runs on your device — the scoring engine itself is part of the page.
Whether a better-scoring room is actually free on your sailing, what the fare difference really is, whether the guarantee rate is worth the risk — and what the deck plan can't show you about your specific week.
Tap a question or the button and an advisor answers against your actual booking — not a generic fleet answer.
