Do please bring US$ or Euros if at all possible to pay any final balances, and to buy tickets etc. from the Boogie itself..

Take some time to familiarize yourself with the exchange rate.. At first glance the Vietnamese Dong seems like Monopoly money simply because such small values are represented by such large denomination notes.. and consequently simple things such as soft drinks and food seem really expensive. They are not, generally!
As a rule of thumb.. 1.6 Million Dong is about US$100.
Try not to get confused between 10,000 100,000 and 1,000,000 Dong notes as that can be a costly mistake!!
