We're laying over at BKK for about six hours and thought a massage would be a good place to pass the time:

1) Any recommendations for airside or landside massage? We are transferring to a regional flight, so have to go through immigration, collect our luggage, and check it in again.
2) What does it cost (or you can just point me to the website)?
3) How much do you tip?
4) Do they have male masseurs or just female masseuses? We prefer the strength of masseurs.

Thanks.
