Allure of the Seas held the title of "the largest ship in the world" until Oasis-class sibling Harmony of the Seas launched in 2016 — followed by Symphony of the Seas in 2018 and Wonder of the Seas in 2022. All Oasis-class ships have now been topped in size by the first ship in a new class, Icon of the Seas, which debuted in January 2024. Still, Allure of the Seas remains formidable — and lots of fun if you love a lively cruise experience — although its long-planned major refurbishment was delayed by the pandemic and hasn’t been completed as of early 2024. Clocking in at a whopping 4,074 guests at double occupancy (and more than 7,000 at full capacity), the ship feels like a small city. In order to help passengers avoid getting lost — or at least get lost less often — the ship is divided into seven “neighborhoods,” all packed with more activities, entertainment, and dining options than you can possibly experience in a week. As a result, Allure of the Seas has a loud, fun atmosphere that feels inspired by the brashness of Las Vegas, with a dash of Orlando theme park thrown in.
