Was in VN (Hanoi) in 2004. Get to Halong Bay if you can before it gets over touristy.
If you want to get off the beaten track, head over to Laos as it's an eye opener. 10 yrs ago it was one of the poorest countries in the world, but now a lot better.
I work in Bangkok right now teaching at a uni so drop in for a drink next trip.
I guarantee there'll be a next trip. Asia stays in your blood like cheap wine.
Enjoy....
