This is by far the best deal on the island. Wonderful staff, and gorgeous view. Excellent prices. You can rent transportation directly from them. It's a little further away from Chawang, but worth it if you're looking for a nice quiet environment; plus it's very close to Lamai, which is a great town with an awesome nighttime market.
Extra room guests were never a problem, and the professionals who keep the place running are excellent guides to a positive and relaxing time. I'm American, but there were folks from all over the world at the resort. The band who plays there regularly are awesome. The place is more like a social club than any other place I've been. I got to have a blast with couples from England, Germany, Russia, France, and the Philippines.
I stayed here for more than two weeks. I had originally planned on going to Vietnam and mainland Thailand, but I just couldn't bring myself to leave this place. It was so relaxing.
The only downside is integrating back into normal society after you get back home. You're truly spoiled here, and it's emotional when you leave.
