I enjoy the lesser developed and less expensive areas of Asia such as Vietnam and Thailand. I would stay away from the more modern and pricey places and try to see Asia they way it was and still largely is, not where it is mostly a copy of western cities. The previous poster's idea about the Malaysian islands is a great idea. I would also recommend going to Bangkok and the north of Thailand, to Saigon and Hanoi in Vietnam (need a visa) and to the mountainous northern areas of VN which are still very wild, remote and beautiful.
