About Icon of the Seas
Icon of the Seas debuted in January 2024 as the world's largest cruise ship at 248,663 GT, since matched by sister ship Star of the Seas (2025), and was the first in Royal Caribbean's new Icon class. The ship is divided into eight themed neighborhoods, including the glass-domed AquaDome performance venue and Surfside, a dedicated zone for young families. It carries up to 5,610 guests at double occupancy and set new records for the largest waterpark at sea.
Best for: Families with kids of all ages will get the most out of this ship, thanks to Surfside, the Category 6 waterpark, and an enormous variety of activities, but couples and groups looking for a "biggest and newest" experience will love it too.

What to know before you book
Cabin tips
The Infinite Balcony cabins are the signature stateroom here. With the push of a button, the balcony converts from outdoor space to indoor living area. Families should look at the Family Infinite Balcony category, which sleeps up to six with a separate kids' bedroom and split bathroom.
Dining
With over 40 places to dine and drink by Royal Caribbean's count, you could have dinner somewhere new every night of a week. Standouts include the AquaDome Marketplace, Hooked Seafood, and the Surfside Eatery for families.
Entertainment
Between the AquaDome aqua shows, the Category 6 waterpark, Lost Dunes mini golf, rock climbing at Adrenaline Peak, and the largest ice arena in the fleet, you will genuinely struggle to fit everything in on a 7-night sailing.
