Yes, Icon of the Seas is significantly larger than the Oasis-class ships, which previously held the title of the world's largest cruise vessels. While the Oasis-class ships (like Wonder of the Seas) have a gross tonnage of approximately 236,000, Icon of the Seas boasts a massive gross tonnage of 250,800. In terms of length, Icon is about 1,198 feet long, just slightly longer than the 1,188-foot Oasis-class, but the real difference is in the volume and capacity. Icon of the Seas can accommodate up to 7,600 guests at maximum capacity (compared to around 7,000 for Wonder) and features 20 decks. It was designed with a focus on "neighborhoods," including the record-breaking Category 6 waterpark and the massive "AquaDome." In 2026, Royal Caribbean continues to utilize this massive scale to provide a variety of "unprecedented" amenities that require the extra square footage, firmly establishing the Icon-class as the new heavyweight champion of the global cruise industry.
