We visited Thailand last year for our honeymoon, we did 10 nights at the Sheraton in Krabi (Nong Thale actually just outside Ao Nang) then 4 nights in Bangkok. We loved Thailand and are planning two weeks next January.
We're looking at 3/4 nights in Chiang Mai and then a beach destination for the remainder. We loved the Sheraton Krabi so much, the area etc. that were just thinking we could go back there, but with such a lot more of Thailand to see we're considering Khao Lak or Samui.
We liked the seclusion and quiet, relaxedness of the Sheraton, so don't want anywhere hustle bustle or very touristy - we only went into Ao Nang for a couple of hours, didn't like it and came back!
Any suggestions of places in KL or Samui that are similar to the Sheraton, with a couple of close by restaurants/bars, would be helpful, or indeed areas in KL or Samui to go to or avoid?!
