Bangkok can be a horrible, sketchy, cover-your-eyes type of place. After a week drinking mushroom shakes and dodging lady-boys, you're gonna want a safe place to gather your shit before jumping on a 12-hour plane ride. If you're balling, the first-class lounge at Suvarnabhumi airport features a spa with private therapy suites and a sauna, exercise and yoga spaces, massages, and all kinds of amazing eats. Now take a deep breath and get that ping-pong show out of your head.
