TUI Cruises, which is a joint venture between TUI AG and Royal Caribbean Group, has historically acquired several ships that originally sailed for Royal Caribbean or its subsidiaries. The most notable transfers involve the Century-class and Oasis-class precursors. Specifically, ships like the Celebrity Galaxy and Celebrity Mercury (from Royal Caribbean’s Celebrity Cruises brand) were transferred and rebranded as the original Mein Schiff 1 and Mein Schiff 2. More recently, the Splendour of the Seas was sold to TUI and eventually became the Marella Discovery for TUI’s UK-based Marella Cruises. The Legend of the Seas followed a similar path, becoming the Marella Discovery 2. These transfers are part of a broader "lifecycle management" strategy where Royal Caribbean moves older, smaller vessels to its European joint ventures to make room for newer, larger "Icon" and "Oasis" class ships in the North American market. This allows TUI to offer high-quality, well-maintained vessels to the German and UK markets at a different price point.
