Hey, I'm looking to spend 4 days and 4 nights at a nice resort in either Krabi, Koh Samui or Phuket for part of my honeymoon in August. This leg of the trip will be after a tour of Vietnam and Cambodia for about 1.5 weeks before hand (I know it's short but it'll wet the appetite for other trips).

Where do you guys think would be the best place. I'm looking for somewhere with not too many people but enough to have something to do at night.

Main hotels I'm looking at are:

1) Rayavadee in Krabi (got a quote for 19,000-21,000 THB per night for one of the nice villas)

2) Six Senses at Koh Samui or Phuket (recommended by a friend who lives in Bangkok and said they are very good)

3) Trisara in Phuket

4) Tongsai Bay in Samui

5) Banyan Tree in Phuket

Those are the ones I've seen by searching these forums. Maybe there are other hotels out there that provide just as nice of a villa type place (with pool) but for a lower price? Looking for the inside knowledge here.

A less crowded beach location would be ideal too...

THANKS!
