Harmony of the Seas

Harmony of the Seas always provides gravity-defying, status-quo denying, electrifying expedition onboard that will set a new standard for family vacations. From first-at-sea feats to the favorites you know and love, you’ll find so many ways to make memories onboard — like the tallest slide at sea, Ultimate Abyss, deck-defying stunts at the AquaTheater, and the robot-helmed Bionic Bar.

Not to mention dazzling Broadway performances and globetrotting gastronomic experiences that go from Asia to the Mediterranean, and beyond. Harmony of the Seas (2016-built, last refurbished in 2021) is the first of all four identical design (Oasis-Plus class) Royal Caribbean cruise ships – with sisterships Symphony OTS (2018), Wonder OTS (2022) and Utopia OTS (2024). Royal Caribbean Harmony ship is the world’s largest passenger liner, exceeding in size and passenger capacity the Oasis-class sisterships Allure OTS and Oasis OTS.

Harmony of the Seas cruise ship deck plan shows a total of 2745 staterooms for 5497 passengers (max capacity is 6410) served by 2400 crew-staff. The boat has 17 decks (16 passenger-accessible, 12 with cabins), 26 lounges and bars, 24 elevators, 9-deck-high Zip Line, 2 rock-climbing walls, 2 FlowRiders, a total of 19 pools. (including 4 swimming pools, 1 kids pool), 9 outdoor Jacuzzis (whirlpool hot tubs, including 2 cantilevered).

The ship’s first drydock was a month-long project (April 2021) at Navantia Shipyard in Cadiz Spain. The docking was for routine maintenance works (done to cruise ships usually every 5 years) to keep them properly maintained. Harmony OTS’s 2021 drydock included mainly technical works (propellers, fin stabilizers, bottom valves, hull painting) and classification inspection.
