Changi Airport, Singapore
Changi Airport is on the list because of the variety of facilities it offers. Its stunning gardens include a cactus garden and butterfly garden, as well as an open-air pool and a pedicure of fish. The airport art collection is a great way to spend hours. If you are late in flight and located in Terminal 3, there is no place to worry about, because you can easily climb down the slide tunnel connecting up and down the floor.
