The Harmony of the Seas was previously the world's biggest cruise ship and still offers the ultimate Royal Caribbean experience. The ship has so much to do and enjoy that there's truly something for everyone. It's constantly buzzing with energy but there are also plenty of spaces for those who want to relax in a peaceful atmosphere.

Adventure seekers will enjoy the ship's Perfect Storm combining three large water slides, as well as their two surf simulators, two rock climbing walls, a zipline, and ice-skating rink. If that's not enough, they also have a feature called The Ultimate Abyss, which is a ten story dry slide accompanied by plenty of flashing lights and loud noises to make it even more adrenaline-packed.
