One of Royal Caribbean's original Oasis-class giants, splitting her year between Western Caribbean round trips from Florida/Texas and a summer season of Western Mediterranean round trips from Barcelona.
Prices vary significantly throughout the year depending on season, demand and how far ahead you book — figures below are typical starting ranges, not fixed prices.
Harmony of the Seas launched in 2016 at 226,963 gross tons, carrying up to 6,780 guests across 18 decks. Highlights include the Ultimate Abyss, the tallest slide at sea; the AquaTheater's high-diving stunt shows; the robot-staffed Bionic Bar; two FlowRider surf simulators; and dining spanning Mediterranean to Asian cuisine across the ship's seven neighbourhoods.
Harmony rotates homeports fairly often within Royal Caribbean's fleet, so it's worth double-checking the exact departure port for your dates when booking.
7 nights, round trip. Fares typically start around $800–1,400pp for an interior cabin on Caribbean sailings, rising to $2,500–3,100pp for a balcony on Mediterranean summer sailings, which run noticeably higher than the winter Caribbean season.
