If you're happy sharing your cruise vacation with 6,779 other passengers (at full capacity), of all ages and with a lot of families, then Harmony of the Seas is about as good as it gets in terms of activities, entertainment and fun at sea -- throw yourself in, and you'll be kept busy all week.

Despite being a massive, family-friendly "mega-ship," Harmony of the Seas is excellent for adults thanks to its distinct "neighborhood" design which naturally separates different crowds. Adults seeking tranquility should head to the Solarium, an ages-16+ glass-domed retreat at the front of the ship with its own pool, whirlpools, and bistro. Central Park is another adult favorite; it is an outdoor area featuring over 12,000 live plants, quiet walking paths, and upscale specialty dining like 150 Central Park and Chops Grille, providing a sophisticated evening atmosphere. The ship also features a dedicated Comedy Club and a vibrant "Entertainment Place" with a Jazz club and a nightclub. While the main pool decks can be noisy with families, the variety of "grown-up" bars like the Schooner Bar and the Bionic Bar (with robotic bartenders) ensures plenty of space for relaxation. For a truly premium adult experience, booking a suite grants access to the exclusive Coastal Kitchen restaurant and the Suite Sun Deck, far removed from the high-energy water slides and children's zones.
