1. The Radisson Blu Berlin is home to the world’s largest cylindrical aquarium, 'AquaDom," (over 82 feet high and 36 feet in diameter) and 2,600 fish of 56 different species. The hotel elevator goes up through the center of the aquarium and, if you're lucky, you might even see a scuba diver during a ride.
2. At the QT Sydney, the in-elevator music adapts to reflect the number of people riding. "Are you Lonesome Tonight" for a solo ride; "Just the Two of Us" for a couple.
3. The 16 illuminated elevators at the Marriott Marquis (top photo) run up and down a mirrored black spiral structure and are a favorite of elevator nerds (yes, they exist) everywhere.
4. At Edinburgh's Hotel Missoni the fashion brand's famous brightly colored stripes and zig-zag patterns are everywhere; including the elevators.
7. At the Philippe Starck-designed Mama Shelter, Paris the elevators are covered in seemingly random trivia.
9. Once upon a time the elevator at The Standard New York housed a delightful Dante-inspired installation by Marco Brambilla that depicted the ride from heaven to hell. Last year, you got to enjoy the experience of another Brambilla installation, in which Kanye West was depicted as a pagan god, surrounded by angels and goddesses.
