1) The most dangerous thing you can do is walk across a huge intersection or through a roundabout. If you don’t get hit by a motorcycle, bicycle, or car, you’ve won the real life Frogger game you’ve been thrust into.
2) Things here are relatively cheap – from a Western world view. You can stay in a decent hotel for $20-$30 USD a night – and that’s talking mid-range price. A meal with a drink will be $5 average in a regular non-fancy restaurant. A bowl of Pho is $2. You get the point.
3) Halong Bay is a beautiful place – a must-see even if you hate “touristy” places. Be prepared to line-up to see some caves and eat a lot of fried food, the fare of choice for boat-cooks for some reason.
4) The level of harassment to buy things is pretty low compared to other countries (e.g. Egypt). Win!
5) “Line-ups” are just crowds of people invading each others’ personal space so they can be first to get checked-in, to get on a bus, to get on a plane, to annoy people, etc.
6) Everyone’s a millionaire in Vietnam.
