An altogether better option (IMHO, Pattaya is to be avoided like the plague) - Aleenta at Hua Hin:

Very small, very exclusive, very beautiful. Get a Pool Suite or one of the Villas, and you will be exceedingly happy.

It can be full of 'celebrities' of dubious worth (the Beckhams - and, apparently, the official Silliest Entourage Ever - left a few days before I got there), but the rooms and suites are very private, so that doesn't really impinge...

I'm sure they'll send a car to pick you up at the airport, if you want - it's two or three hours' drive from Bangkok.
