On Royal Caribbean's giant Oasis-class ships, there are multiple pool areas, watery play zones, rock climbing walls, surfing simulators, miniature golf courses, basketball courts and even zip lines. The line's biggest ships are bigger than any other cruise vessels afloat, and they're chock-full of more restaurants, bars, entertainment zones and attractions than you'll find anywhere else at sea - or even at many of the biggest land resorts. For megaresort lovers, Royal Caribbean may be the ultimate cruise line.
