We are looking for a quiet resort in Thailand, possibly on an island other than Phuket?

We will be heading back to Phuket in Feb and would like to go somewhere afterwards. We are looking for a quiet location/resort on the beach where we can do some snorkelling and fishing, within walking distance. Does anyone know of a four star resort that doesn't charge huge prices for food? Places we have been looking at are Koh Tao, Phi Phi, Koh Lanta... Any suggestions?

If you go for a quiet getaway, try Ko Lanta island. Just an hour from Phuket by boat. tranquil beaches, magical sunsets.

I'd recommend for the Pimalai resort and Spa http://www.discovery-thailand.com/Lanta%20Islands%20hotels.html , it's one of the region's most talked about boutique resorts.

Layana Resort is also a good choice. you two can laze in the privacy of your own living area, and bask in warm tropical sunshine.... it's a must to try luxurious treatment at their "Linger Longer" Spa.
