Does anyone have any recent information about the whole visa on arrival thing? I'm debating with whether or not it will be easier to get an actual visa (loose leaf or sticker) before hand opt for the approval letter and visa on arrival. Also, has anyone done a re-entry visa (I'll be going to cambodia for a week and then returning to Hanoi for a day before my flight leaves) or is it easier to get a multiple entry one? The money isn't a big deal to me (seems like the multiple entry visa--either loose leaf or actual sticker--is going to run me about $100-150 depending upon if I do a rush and wait the half hour at the consulate the next time I'm in San Francisco or just send it off to them) but it does feel like a hassle. On the other hand it feels more secure and 'assured'. The on arrival seems like you can do most of it online with minimal fuss but in the end feels like a bit of a question mark to me. Plus there is the supposedly long wait for processing when you arrive. Pick your poison, right? Has anyone done both or have a strong feeling on one way or the other based upon positive or negative experience?
