ah, ok. i think this must be how I got confused. I knew I'd seen someone say something about booking in advance for Vietnam. it must have been this appointment
And unfortunately, I couldn't get a flight direct to HCMC before my current visa ended. So I went for Hanoi instead. Read a couple of peoples posts about it. And it doesn't sound too bad either. Fingers crossed
Anyway, really appreciate your help and all the links. Big help
