Marina Bay Sands Singapore

The Marina Bay Sands hotel in Singapore opened its doors in 2010, to the tune of a whopping $5.7 billion. That amount paid for the massive 2,561-room hotel, a museum, casino, restaurants, bars, a swanky shopping mall, and the pièce de résistance: the SkyPark, an insane rooftop pleasure dome with a 150-meter (492 ft.) infinity pool.
