Pennie (my wife) and I haven't been back to Thailand for over a year now, so are planning to visit next January. We don't want to return to where we've already been, because we want to explore more of this wonderful country. Our favourite places we've already been to are Khao Lak, Ko Lanta and Ko Chang. We've also visited Phuket, Krabi and Ko Samui, but none of these really impressed us in the same way. Similarly we don't really fancy Ko Phi Phi. We do love beach based holidays, but always hire a car and drive around exploring whilst away.
Thanks in advance for your help, take care, DrMike.
PS. I've posted this on the forum pages of our three favourite places to get maximum input from the experts. Sorry if this is annoying to anyone.
