The famous pool @ Marina Bay Sands, Singapore. Take a swim stories up, in an infinity pool "overlooking the Singapore skyline in the tropical oasis of the Marina Bay Sands." Terrifying, but still on my to-do list.
The trio of towers that make up Singapore's Marina Bay Sands include hotel rooms, a museum, a casino, a convention center, and a waterfront promenade. (Courtesy Timothy Hursley / Marina Bay Sands) From: The Hotel World's Most Striking Architecture.
