This is the confusing thing here... various people have said I've not explained what I'm looking for, but then you go and say exactly what I'm looking for. Clearly I'm not being ambiguous if you can nail it on the head in one go.
I'm thinking I may hit Pattaya for a few days, the hotels are fairly cheap it seems compared to other places, and its not that far from BKK.
I like some of the suggestions people have put out here, gonna do some more research, and see where it takes me.
