Have a Great Time LAG
That's a good price for the ticket, I think I spent more than that and it was over 10 years ago.
I read that Thai Airlines is only running about 50% full on flights into the country so hopefully you have room to spread out on your flight. I'd join you but I'm getting too old and would only slow you down, besides I have family responsibilities right now.
You should probably head straight down to Pattaya because of the beach and also the much cheaper prices than Bangkok. I've heard the bars are almost empty in Pattaya but the booze and the girls have not reduced their prices, but you won't have much competition.
Give us a full report when you get back, you're gonna have a great time...
