Quantum of the Seas Features

You'll also find iFly skydiving simulators, bumper cars, and SeaPlex – the largest indoor activity space at sea. The dining scene features molecular gastronomy and innovative concepts alongside traditional options.
Adventure of the Seas Experience
Adventure offers that classic cruise ship feeling many people actually prefer. With more space per person, the ship never feels as crowded. You get the traditional promenade, rock climbing wall, and ice skating rink that made Voyager Class ships famous.
The entertainment leans more traditional – think Broadway-style shows, comedy clubs, and piano bars rather than high-tech spectacles. Some passengers find this more relaxing and authentic to the cruise experience they remember and love.
Which dining options are better?
Quantum of the Seas definitely wins on variety and innovation. You'll find everything from robotic bartenders mixing your drinks to specialty restaurants serving molecular gastronomy. The main dining rooms offer more diverse menus with rotating themes.
