Royal Carribean’s Harmony of the Seas is one of the biggest ships in the world, and onboard is a world of thing to do. There's the Ultimate Abyss, with the first-ever 10-story shipboard plunge, as well as the exhilarating multilevel Perfect Storm slides. As the kids explore Splashaway Bay, take a tree-lined stroll through Central Park, or find your own haven in any of the other seven iconic onboard neighborhoods. Sip a post-dinner cocktail crafted by a robot in our unique Bionic Bar, and share every moment with not just your family onboard, but friends back home with the fastest Internet at sea. Discover the biggest, boldest family vacation ever on a ship unlike anything else on the ocean.
