Considering the Paramount Hotel Singapore in Singapore?

How pleasant Airports can be... by divandrea
Singapore Changi is probably THE transit airport in Asia. So if you have to kill a few hours before travelling to Australia or Europe, and you would like to allow yourself something: go to the airport spa. Have a massage or rent a whirlpool. After and before a long distance flight, you just feel completely relaxed. It's definitely worth while!

P.S.: It's not my favorite thing about Singapore, but about Singapore Airport...
