Here's another one I have been checking out for our trip in march, I would also like to hear from anyone that has been...if any.
My personal plans are to be in phuket for a week or so, then spend a few of my last days recouping from the attack of the alcohol induced stupur syndrom, so far this place looks like a great retreat for just this purpose...mind you nothing fancy for me, I prefer the route less traveled and I'll be pampered plenty while in patong.
Its Koh Racha Yai..I am attaching a photo borrowed from the web.
