We loved our time last year near Hoi An in Vietnam. The town itself is very touristy, but that brings its own attractions and the beaches were beautiful, warm water, lots of cheap and tasty food. You can live like a king for very little money, but don't be scared of trying the local eateries. We can't wait to get back.

I hope you get there is August. I'd definitely be booking everything refundable or leaving it to the last minute.
