We are going to be there in July and August.
Please tell us, taking into accoint your experience, how we should do it logistically?
We will arrive in Bangkok. About flight back we are not sure yet if you should book round flight or one way to Bangkok and then come back from different place.
Our aim is too see as much as possible with a little time on the Thai beach (we were thinking of koh samui it should be nice there despite of low season).
If my description is too general please tell me so I will try to be more specific.
