Ohhhh yes!! Done a pre full moon party and a full moon. My girlfriend and I went December 2009. We stayed well away from Haad rin as its pretty dodgy (thief's operate in this area) and accommodation isn't good! You can stay pretty much anywhere on the island and get back and forth. Taxi's are everywhere!
I will give you a very good bit of advice for when you are partying. When you go to buy your drinks (Buckets) from one of the 10,000 drink huts, get them to give you the bottles and poor it yourself! I caught them swapping a bottle of Bacardi for something else and they are all doing it!! please trust me on this! It spoilt the night when i caught them doing it because I couldnt trust anyone making drinks!
Its one hell of an experience though!! You will love it! Stay away from the flaming skipping rope too!! Seen some nasty wounds pottering about!
Thanks for the tips...but i think a flaming rope will be too enticing when im trollyed :
Would you suggest staying towards the upper end of the island?
