Hi, I actually cancelled that booking, it was quite expencive, but the main reason was that I wanted to be close to the full moon party and that place is a bit of a drive.
If you dont mind catching a lift to Haad Rin for the party then that place I hear is very nice. I wouldnt worry about the price as the prices skyrocket when it gets close to full moon time, and no doubt new years if you dont have bookings.
