Wonder Of The Seas deck 4 plan (Entertainment Place-Casino-Studio B)

Royal Theater (complimentary, total capacity 1401 seats, upper/orchestra level 2 of 3) is the ship’s main show lounge for Broadway-style dance and music productions and aerial acrobatic performances in the evenings. The theater presents nightly 2 grand shows – early (at 8 pm) and late (at 10 pm) to match the assigned dining room sittings. Both are full-length production shows specially designed for the cruise ship – with professional performances (singing, dancing, acting, live band music), excellent decors and lighting. Signature shows are “Hairspray” (musical comedy / original Broadway production themed on humor and commentaries on early 1960's race relations) and "Flight" (themed on the history of flying). Other theater entertainment options are the rotating Headliners (tribute band show) and popular game shows (like “Love and Marriage”). Royal Theatre has its own bar for refreshments. During the shows, waiters walk around and offer bar service. During the day, the theater functions as cinema (incl DreamWorks 3D movies) and also hosts enrichment lectures and bingo playing sessions. Royal Caribbean’s Snowball Jackpot Bingo offers most generous payouts (final jackpots are in several thousand dollars). Among the bingo prizes are also free cabin upgrades and even free cruises.

Studio B (ice rink theater /balcony level 2)

Entertainment Place (neighborhood/nightclub district) offers daily live performances and demonstrations (incl cooking demos and DreamWorks characters meets-greets).

Comedy Club (“The Attic”) is an adult comedy lounge with its own bar and live stand-up comedy acts nightly. Adjacent to the club is the Crown & Anchor room.

In June 2025, the casino complex was expanded with the Non-Smoking Casino Royale, a gaming room fitted with 40x slot machines, 1x blackjack table, 1x poker table. The new Non-Smoking Casino occupies the space of the former Golden Room and the Crown Lounge (fka Diamond Club Lounge/relocated to Deck 16).

Art Gallery displays original artworks available for purchasing at discount prices (allegedly cheaper than at land galleries).

Casino Royale is a large-capacity, Vegas-style gambling casino with 456 slot machines, 27 gaming tables, poker room (for high-stake players), full-service Casino Bar Lounge (seating area with plush chairs and sofas). The Casino staff also provides complimentary gambling lessons. Regularly, here are hosted gambling tournaments. The list of available games includes Video Poker (machines) and table games (Craps, Roulette, Black Jack 21, Caribbean Stud Poker). Guests can pay in cash, with their “Sea Pass” cards or with their WOWbands. The Casino is a smoking-allowed area, but also has a small non-smoking section.

Izumi Japanese Cuisine (menu, portside) is the RCI’s signature pan-Asian cuisine specialty restaurant with mostly traditional Japanese dishes (sushi-teppanyaki-hibachi, tableside cooking). The restaurant is a la carte priced and open for Lunch (seadays only, between 12-1:30 pm) and Dinner (between 6-9:30 pm). The restaurant is comprised of a sushi bar (sushi/sashimi) and a Hibachi room (another section with 2 cooking stations). Reservations are required for the hibachi room only (not for the sashimi-sushi room). The menu includes sushi rolls, signature rolls, sashimi (2- or 5-piece, also combo platter), sukiyaki, yakimeshi, ishiyaki (grill / chicken, beef), wakame salad (seaweed), pan-fried gyoza dumplings (pork), hot/cold appetizers, premium seafood (tempura, tuna, shrimp, lobster, eel, crab), noodles, desserts (ice cream, pancake, caramel flan, dessert sampler) and specialty drinks (cocktails, beer, sake selection). Edamame soybeans and miso soup are complimentary. Izumi has Teppanyaki menu (for iron griddle-cooked food) and Omakase menu (Chef’s choice).

Izumi Express is the Royal Caribbean’s new “sushi to go” option available fleetwide since July 2016. The “take-out sushi” is fresh-made and of premium quality. The new option is a great choice for families with kids (avoiding the formal sit-down meal) and for all passengers willing to enjoy this popular Japanese food somewhere else on the cruise ship (incl in their cabins). Izumi Express sushi ordering is via phone (anyone on the ship, incl the cabins) and also by going to the Izumi restaurant and placing your order there. Guests can order any item from Izumi’s sushi menu during the restaurant’s operational hours. The staff takes the order and provides a time window to pick it up (usually within 10-15 min). Meals are in to-go containers (plastic, transparent) and conveniently bagged up. Quick and easy takeaway service is provided by the new Izumi Express carts (colored in black) offering up to 8 pre-packaged sushi rolls.

Main Dining Room (mid-level 2 of 3) is an aft-located complimentary restaurant for Dinner only, with 2 fixed sittings - at 6 or 8:30 pm, plus the flexible My Time Dining program.

A total of 24 elevators (12x forward + 12x aft) provide access all the way to deck 16, while decks 17 and 18 are accessed by 6 lifts.
