Airport at Reykjavik, Iceland. We had an unexpected extra 2 hours there.
Ladies room at that airport. Each stall is a fully-enclosed room with a fancy Dyson-designed faucet that has a water mode and a Dyson hand dryer mode.
It works really well.
One of the prettier parts of Iceland, seriously. They do have farms and areas where things grow, but I didn't see any of them from the airplane.
