Wish and Treasure are sister ships of the same class, so their size, layout and cabin categories are broadly identical — the differences are thematic and in the specific restaurants and lounges, which means the honest way to choose between them is by itinerary and sailing date rather than by ship.
Sister ships are the hardest comparison to write honestly, because the commercial incentive is to manufacture a difference and the truth is usually that there is very little in it. That is broadly the case here — but not entirely, and the differences that do exist are concentrated in a few specific rooms rather than spread across the ship.
What sister ships means in practice
Wish and Treasure are the first two ships of the same class, built to the same design at the same yard, with Treasure the later of the two. A third, Destiny, follows them. When a line builds a class it reuses the hull, the machinery, the deck plan and the cabin arrangements, because that is most of the economic argument for building more than one.
So the things people ask about first are the things that are identical. Size, tonnage, passenger capacity and deck count are the same. The cabin categories are structurally the same — the same layouts, the same square footage, the same locations. The public spaces are in the same places, which means someone who sailed one will find their way around the other on the first morning without a deck plan.
That is a genuinely useful thing to know if you are choosing between them, because it removes about eighty per cent of the usual comparison criteria in one go. It also means anything you read describing one of them as “bigger” or “more spacious” is describing a feeling rather than a specification.
Where they actually differ: the themed spaces
The differences are thematic, and they are concentrated in the restaurants and lounges. Disney gives each ship in a class its own identity by dressing the same rooms differently and, in some cases, replacing a venue outright.
The clearest example is in the rotational dining. Both ships use the same three-restaurant rotation structure, where you move between dining rooms across the sailing and your serving team moves with you. On Wish, the distinctive one is Arendelle, a dining experience themed around Frozen. On Treasure, that slot is Plaza de Coco, themed around Coco, which runs as a dinner with live performance across two seatings during the voyage.
The lounges differ too. Treasure carries the Periscope Pub where Wish has Keg and Compass; Skipper Society where Wish has The Bayou; and Sarabi, themed around The Lion King, in the space Wish uses for the Luna lounge. Treasure also carries the Haunted Mansion Parlor, which has become the venue people specifically ask about.
That is a real difference in character, and for some families it is the deciding one. It is not, however, a difference in what the ship does. Both run the same rotational dining model, the same kids club structure, the same entertainment format.
Does it matter for the children?
Less than parents expect, which is consistently the answer we give and consistently not the answer people want.
The kids club provision is comparable across the two ships — same structure, same age bands, same nursery arrangement for the youngest children. A child who would have a good week on one would have a good week on the other, and the youth staff are running the same programme.
Where theming genuinely matters is if a specific child has a specific attachment. A five-year-old deeply invested in Frozen will have a better week on Wish; a family that particularly wants the Coco dining experience should take Treasure. Those are real preferences and worth acting on. But they are preferences about two or three rooms, and framing them as a choice between two different ships overstates it considerably.
For families weighing Disney against the alternatives more broadly, that is a bigger question than which of these two hulls you take. Our family cruise guide covers how the age of your children should drive that decision, and it matters far more than this one does.
The newer-ship question
Treasure is the later ship, and there is a standing assumption in cruising that newer is better. It is worth unpacking rather than accepting.
What newer genuinely buys on a sister ship is the accumulated refinement: a yard building the second of a class corrects the things it learned on the first, usually in flow, service areas and small operational details rather than anything a passenger would name. It also buys wear — the newer ship’s soft furnishings and surfaces are simply less used, which is a real if unglamorous advantage.
What it does not buy is a better holiday, because the older of the two is still a recent ship maintained to the same standard. If the gap were fifteen years this would be a different conversation. Between two ships of the same class, newness is a tiebreaker rather than a reason.
What is the same, and worth knowing either way
Because the class is shared, a number of things people research separately for each ship are simply the same on both, and knowing that saves a lot of comparison effort.
The cabin experience is identical in every meaningful respect: the same categories, the same layouts, the same split-bath arrangement in the standard staterooms, the same verandah dimensions. If you have read a review of a cabin category on one ship, it describes the other.
The dining structure is the same. Both run rotational dining, where you move between three main restaurants across the sailing and your serving team travels with you — a model that is genuinely unusual in cruising and one of the more distinctive things about sailing with this line. Both carry the same adults-only dining venues and the same approach to the buffet and casual options.
The onboard spaces that are not themed differently — the pool decks, the theatre, the adult areas, the kids club footprint — are in the same places doing the same things. So is the entertainment format, even where the individual shows differ.
How to actually choose between them
By itinerary, date and what the sailing costs on your dates. That is not a dodge; it is genuinely where all the meaningful difference lives when the ships themselves are this similar.
The itinerary is the largest variable. These ships are deployed on different routes at different times of year, and the difference between a short Caribbean sailing and a longer one, or between two different sets of ports, will affect your holiday far more than which lounge is on deck five. If one of them is doing the itinerary you want in the week you can travel, that is your answer and you should stop comparing hulls.
The date is the second. School holidays, hurricane season, the weeks either side of peak — these change both what you pay and how busy the ship is, and they change it by more than any thematic difference is worth.
The third is what each is actually selling for on your dates. Two near-identical ships frequently price differently in the same week for reasons of deployment and demand rather than quality, and there is no sense in paying a premium for a sister ship difference that amounts to a different lounge. Our Disney Caribbean sailings page is the place to see how the two are deployed across a season.
If you have sailed one, is the other worth doing?
Yes, but not primarily for the ship. If you loved a Wish sailing and are wondering whether Treasure is a new experience, the honest answer is that it is the same experience in differently decorated rooms, with a handful of genuinely new venues.
That is not nothing — the rotational dining rotation being different means your evenings are different, and the added lounge spaces are the sort of thing repeat cruisers notice. But if you are choosing a second Disney sailing purely for novelty, a different itinerary on the ship you already know will feel more new than the same itinerary on the sister.
The exception is families who have done the same route repeatedly and specifically want the newer ship’s spaces. That is a reasonable thing to want, and it is worth paying a modest premium for if the dates work. It is not worth reshaping the holiday around.
Common questions
Are Disney Wish and Treasure the same ship?
Same class and layout; different theming and some different venues.
Which is newer?
Treasure is the later of the two.
Does the choice matter for kids?
Less than parents expect; the kids club provision is comparable.
How should you choose between them?
By itinerary, date and price for your dates, not by hull.
So the recommendation, since a comparison ought to end with one: take Treasure if the itinerary and dates are equal, because the later ship carries the newer spaces and the small refinements at no cost to anything else. But do not choose Treasure over Wish if it means a worse itinerary, a worse week, or a materially higher fare — the difference between these two ships is a handful of rooms, and the difference between a good itinerary and a compromised one is your entire holiday.
If you want to see how the two are deployed across the season and which sailings line up with your dates, that comparison is straightforward for us to run across the whole Disney fleet — and it costs nothing, because the cruise lines pay our commission and your fare is the same as booking direct.
