Yes, Oasis of the Seas has undergone significant refurbishments since its debut in 2009, most notably a massive $165 million "Royal Amplification" in late 2019. This transformation added several "Oasis-class" staples that weren't originally on the ship, such as the Ultimate Abyss (the tallest slide at sea), The Perfect Storm water slides, and the Portside BBQ restaurant. The pool deck was completely reimagined with a Caribbean theme, and new venues like the Spotlight Karaoke and Music Hall were introduced. More recently, in October 2024, the ship underwent another scheduled drydock at the Navantia shipyard in Cádiz, Spain. While the 2024 refit was primarily focused on routine technical maintenance, class inspections, and freshening up public areas rather than adding major new attractions, it ensured the vessel remains in peak condition. As of 2026, the ship continues to offer a modern experience that rivals newer vessels in the Royal Caribbean fleet thanks to these iterative updates and the major 2019 overhaul.
