Mega-ships — wow-factor cruise ships with theme park-like amenities and room for thousands of guests — have been around since the mid-2000s, but when MSC Cruises decided to max out its already sizeable mega-ship fleet with 2022's MSC World Europa, the almost-7,000-guest vessel nabbed a spot on the list of the world's top 10 largest cruise ships. It has since been joined by 6,764-guest MSC World America, which in April 2025 began sailing seven-night Eastern and Western Caribbean itineraries year-round from Miami, adding an exciting new option for families, couples, and singles seeking a fun and affordable escape at sea.
World America's massive size is evident as it looms over the new four-story MSC Miami Cruise Terminal at PortMiami or the cruise line's private island in The Bahamas, Ocean Cay MSC Marine Reserve. The 22-deck ship features seven districts (including the upscale MSC Yacht Club ship-within-a ship), 19 restaurants, 18 bars and lounges, three large entertainment venues (World Theater, Panorama Lounge, and Luna Park Arena), seven pools, 14 hot tubs, four waterslides, one dry slide, a ropes course, and thrills such as Formula One racing simulators, bumper cars, and the Cliffhanger, which swings guests 164 feet above the ocean.
