This fleet’s 22 vessels include the world’s two largest cruise ships afloat—the 5,400-passenger Oasis of the Seas and Allure of the Seas—and the line’s stops include ports in Asia, Australia, the Caribbean, Europe, and South America, among others. On board, there are tons of activities to choose from, including rock climbing and ice-skating. Quantum of the Seas, a futuristic new vessel that includes tech-y touches like increased Internet connectivity, and, yes, a robot bartender, debuted last fall.
