If you think of airports as the place you have to go before you get to where you want to be, the Singapore Changi Airport might change your mind.
Terminal 1 is home to a seven-story Rain Vortex, the world's largest indoor waterfall that plunges into a rainforest. If you get bored there, you can climb a rock wall, go to a movie, visit a butterfly garden or swim in a rooftop pool. In Terminal 2, you can enjoy a bar staffed by a robot and a digital sky.
It's the most lavish entry in the class of airports that are becoming a destination themselves.
