If you are in Ho Chi Mihn City in the south, you will want to visit Siem Reap, Cambodia before going to Hanoi in the north. On arrival in Cambodia we had to pay $20.00 each for the visa and around $25.00 each for the exit tax when we left.
Have a great trip.
The $25 tax is only applicable when leaving the country by air. You don't pay this on ground transportation, which is why I suggested flying into Cambodia (to avoid border touts and visa bribes, big problem along the Thai border, not to mention the diabolical road from Poipet to Siem Reap) and then continuing on by land.
BTW, since no one has mentioned them yet, check out
