If you just get a cab at the airport you will likely get ripped off. (Only by a few hundred baht, but its the principle)
Also a lot of those guys won't know where the Pattaya hotels are.
There are guys from Pattaya who will meet you if you pre-arrange by email, between 1000 and 1300 b.
If you want some contact details, I can put them up for you.....Jonny maybe a good idea just to pin acouple of email addys for new guys to check out the taxi services?...I'll do it tonight
BTW, Welcome to the board, hope you stick around.
