My girlfriend and I have been to Thailand a few times. We used to enjoy time on Koh Phangan as part of our stay. My gf still loves it there but for my reasons I've become a bit tired of this lovely island. We have about 10 days stay and I'm looking for other options but for her a beach would be good. We both loved the feel to places like Krabi Town, Chang Rai, Pai, and Mae Hong Song. I liked the people very much in these places, they didn't seem too jaded of tourists and polite, also reasonably cheaper was a nice bonus. Kanchanaburi, Erawan Falls were good too. So is there any recommendations for somewhere to go that you might have enjoyed that and we might not have been, excluding the big destinations there on offer.
I know the question is a bit vague but your replies would be appreciated and of help to me in kick-starting some research.

A place where i didn't see any other tourists was Samut Sonkram and the Ampawa floating market which is awesome. You can stay at homestays on the river, very relaxing except for the Mosque across the river.
I'm sure you will find some info if you google it.
