Royal Caribbean has completed an extensive renovation of the Harmony of the Seas, unveiling the largest casino within its cruise fleet as the company enhances its onboard gaming experiences.
The vessel, which debuted in 2016, recently emerged from a five-week drydock in Europe as part of the cruise line’s “Royal Amplified” initiative, according to Parade. This renovation affected various areas including entertainment venues, dining options, pool decks, bars, and guest accommodations.
The most notable transformation took place on Deck 4, where Royal Caribbean expanded the Casino Royale by converting several entertainment venues into additional gaming areas. The redesign involved the relocation or removal of spaces like the Attic Comedy Club, Jazz on 4, and the Crown Diamond Lounge.
With these changes, Harmony of the Seas now boasts over 500 slot machines and 37 live dealer table games, making it the largest casino currently within Royal Caribbean’s fleet of 28 ships. Guests can enjoy a wide range of classic casino games, including blackjack, roulette, craps, baccarat, and three-card poker, in addition to Texas Hold’em options.
Alterations in Entertainment Spaces
In order to make way for the expanded gaming area, several familiar venues were significantly modified. The Crown Lounge has been relocated to Deck 15, transforming part of the former teen club area into a new lounge with ocean views.
The cruise line also redesigned many public gathering spaces aboard the ship. The pool decks now feature a tropical theme centered around The Lime & Coconut bar concept. Dining options have been enriched with a complimentary Mexican restaurant and a Brazilian steakhouse that offers tableside service.
Additional new amenities include a sports bar and arcade outfitted with numerous TVs and retro games. A tiki-themed cocktail venue has replaced the previous robotic bar concept.
During the drydock period, engineers added nearly 100 staterooms by reconfiguring interior spaces on the ship. Some of the new accommodations include panoramic suites with expansive ocean views located above the bridge. Additionally, a previously underused conference center has been transformed into more inside cabins.
Harmony of the Seas has resumed operations with summer sailings in the Western Mediterranean, exploring destinations in Spain, France, and Italy. After its European season, the ship is slated to cross the Atlantic for year-round itineraries in the Caribbean and the Bahamas from Port Canaveral.
Cruise Industry’s Growing Emphasis on Gaming
Royal Caribbean’s expansion mirrors a broader trend among cruise lines that are increasingly focusing on casino entertainment. With gambling becoming more mainstream in the U.S., particularly due to the rapid growth of sports betting, cruise lines are enhancing their gaming-oriented attractions.
The company has also enhanced its fleet with more smoke-free casino sections by converting Jazz on 4 lounges into gaming areas where smoking is prohibited. Guest surveys indicate that passengers are more inclined to gamble in smoke-free environments, reflecting declining smoking rates.
Other cruise operators are similarly expanding their gaming options. For example, Carnival Cruise Line recently introduced adults-only casino-themed voyages called ACES (All-Casino Exclusive Sailings), which feature promotions and tournaments centered around table games and slots.
Despite this growing focus on onboard gambling, some travelers have voiced their concerns. Online feedback highlights a sentiment that cruise lines are prioritizing casino space at the expense of other amenities. Comments included observations about overcrowding on pool decks and the potential for ships to be humorously dubbed as “Casino of the Seas.”
Casinos at Sea: Industry Standards
Casino operations aboard cruise ships adhere to gaming standards that reflect regulations similar to those in Nevada casinos. The Cruise Lines International Association mandates that member companies comply with practices akin to those enforced by the Nevada Gaming Control Board.
According to Nevada regulations, slot machines must maintain a minimum payout rate of 75%. While land-based casinos often set their payouts between 85% to 90%, cruise ship slot payouts usually range from 80% to 85%.
Though payouts at sea may differ from those on land, cruise operators are still obligated to ensure fairness and provide consumer protections for passengers using casino facilities.
