Celebrity Xperience has 24 cabins on two decks (two, Boat Deck and four, Main Deck). Although there are only three categories, Elite Ocean View, Premium Ocean View and Deluxe Ocean View, accommodation comes in various shapes and sizes.
Each cabin has a double bed or twins that can be pushed together; fixed reading lights; a small vanity; a wooden wardrobe with decent hanging space and several deep shelves; a safe; and a nightstand with drawers. Colors are neutral, in cream and beige with warm wood, with bright photographic prints of Galapagos animals on the walls. There's either a large picture window or a pair of portholes for the lower grades; there aren't any balcony cabins.
Every cabin gets a pair of flasks for water -- these are very useful for trips ashore, as well as being good ecological practice, and you can take them home (there are filtered water dispensers on every deck). There's a hair dryer, and a big mirror, as well as bathrobes, a mini-bar stocked with sodas, and a TV, although this only shows fuzzy local channels; reception in the islands is poor. Bathrooms are compact, with a shower, toilet, small basin and Ecuadorian-made bath goodies in dispensers. Electrical sockets are dual 110/220v. Cabins are serviced twice a day. There's a washing line in the bathroom but because the air conditioning is fairly strong, it's difficult to dry things quickly.
Deluxe Ocean View: These are the cheapest accommodations, all on Deck 2, with two portholes and 165 square feet of space, so fairly compact. The facilities are the same as in the more expensive cabins, though. Although all these cabins are midship, they are subject to some engine and anchor chain noise.
Premium Ocean View: There are eight of these 175-square-feet staterooms on Deck 4, with big picture windows. You won't get engine noise up here but you can feel the roll of the ship.
Elite Ocean View: These are the most expensive cabins, a generous 200 square feet each, located forward on Deck 4. There are only four of them. Rooms 400 and 401 are forward facing and L shaped, with the long side of the L used as a storage area, where the wardrobes are located. These cabins have forward-facing portholes as well as a picture window on the side. Rooms 402 and 403 are a squarer shape and can take a third bed.
