Have a look at "Maenamburi resort" on Meanam beach,you can get a beachfront bungalow for $80 odd dollars a night with the beach at your doorstep,We had a bungalow like this on Koh Chang in Kai Bae beach for 3 night and didnt want to leave. I t is fantastic to wake up and walk into the sea just meters from your door.

I have been told its a bit quieter in Maenam but good for a few night and easy access to the ferry to Kho Phangang.

We will be staying there for at least 4 nights before going to Bangkok.
also thinking about the Salad huts on Phangang,and a real cheapy Al's huts in chewang for a couple of nights just to get our bearings.

looks like you did your reserch on the "Evergreen" as it only got a couple of bad reviews early last year when there was a bit of building work going on.
