There's never been a cruise ship like this. Enjoy one-of-a-kind features like an ice skating rink, the Royal Promenade and a rock-climbing wall. There was only one way to accommodate all of these innovative ideas. Royal Caribbean built a bigger cruise ship. The 138,000-ton, 3,114-guest Explorer of the Seas offers more space for every guest, plus enhanced staterooms, expanded dining options and exceptional recreational facilities.
