I just got back last week. I had a great time.
I will be posting my "review" of the place shortly. Stand by.
Anyway, I recommend going to Pattaya for action. It's a beach resort town about 2 hours by bus from Bangkok.
I stayed in a condo rather than a hotel. It's cheaper, nicer and more "guest" friendly. PM me if you want some information about where to stay.
The taxis are crooks. Beware.
Enjoy and don't forget to wear a rubber thingy on your thingy.
