I was just wondering what bits were good to go and check out as it's been ages since I've been there (3 years) and am thinking of going later this year.
I've been to Koh Samui, Krabi and explored Bangkok extensively. Where else would be cool to holiday that isn't TOO built up but still remote enough to have some space to chill.

Thanks

(sorry aware that travel agents can also do this but thought first hand experiences might be cool).
