RE: My last Thai visa is in my passport

You can't really argue with that view! I think you are going to be really happy in Vietnam. From what I have heard, it is a really great place. I'd like to visit there someday. Chances are I will never make it though. My wife has some places out of the country she wants to visit that take precedence over my wishlist. To be fair most of the stuff on her wishlist is on mine as well, so it really isn't a win/lose situation. Good luck getting your final VISA sorted out. I'd probably just switch my flight, even if it cost more. Just to avoid having to deal with them one last time!
