Royal Caribbean International

Royal Caribbean is the cruise line for you if you want to feel like you're living in a floating metropolis, since it features four of the world's largest cruise ships. In terms of passenger count (about 6,700 at full capacity), length (almost 1,200 feet), and gross tonnage, Symphony of the Seas, Harmony of the Seas, Allure of the Seas, and Oasis of the Seas are at the top of the list (more than 225,000 tonnes).

Given their size, these ships provide every luxury you can think of—and many you can't—from waterparks to world-class musical shows to autonomous bars manned by robots to double-decker suites with kid-friendly slides. These behemoths may be seen sailing the Caribbean and Mediterranean all year, but with so many activities on board, you might not want to leave.
