Everyone loves a winner—and apparently Icon of the Seas is just that. In last month’s analyst call, Royal Caribbean International CEO Michael Bayley reported that Icon’s load factor is running around 132%, meaning every cabin is full, often with three or four guests.

So it’s no surprise that in a bigger-is-better world, Royal Caribbean would be doubling—or even tripling—down on its ace in the hole. Today it did just that, announcing an agreement with Finnish shipbuilder Meyer Turku for a fourth Icon Class ship, due for delivery in 2027, plus options to build two more.

RCCL’s largest ship ever, Icon of the Seas launched in January 2024. A second Icon-class ship, Star of the Seas, already is on sale, scheduled to debut in August 2025, and an as-yet-unnamed third sister will join the fleet in 2026. (Also this year RCCL welcomed Utopia of the Seas, Silversea’s Silver Ray and TUI Cruises’ Mein Schiff 7, and announced a seventh Oasis Class ship for 2028.)

“Icon of the Seas is unlike anything the world has seen before, and we’re just getting started,” Bayley said in today’s announcement. “We are leading the vacation industry in developing new experiences for our guests to create lifelong memories, and we continue dreaming and evolving to deliver more ways to chill and thrill.”

Even as some pooh-pooh the trend toward larger and larger ships (Icon carries 5,610 passengers, about 200 more than Oasis class), Icon and Star have been selling faster than any other ships in Royal Caribbean’s 50-year history.

Icon-class ships feature eight distinct neighborhoods; over 40 restaurants; 28 cabin types, including a three-story Ultimate Family Townhouse; and the biggest water park, the tallest drop slide, and the biggest swimming pool at sea. They also have the Royal Promenade and Central Park familiar from the Oasis-class ships, as well as new elements like the family-oriented Surfside neighborhood, plus two new top-deck recreation areas, Chill Island and Thrill Island. The aqua shows have moved to an AquaDome, a huge glass-enclosed space with a 50-foot waterfall, while the Royal Promenade adds the Pearl, a multi-sensory walkway. There is a dedicated suites-only neighborhood—and you can have your own private butler. (For more on the joys of butlers, see Finding Peace and Quiet – and a Great Butler – at Breathless Montego Bay.
