Should I take my money to Vietnam in cash or travellers cheques?
Vietnam’s official currency is the dong, which can not be purchased outside Vietnam. The main banks in Hanoi and HCMC can handle a fairly broad range of currencies nowadays, but the dollar is still the most widely accepted. I therefore recommend taking a combination of US$ cash and US$ travellers’ cheques, with the bulk in travellers’ cheques for safety. American Express, Visa and Thomas Cook cheques are the most recognised brands. It’s a good idea to arrive with at least some small denomination dollar bills ($1s, $5s and $10s) to get you from the airport into town and to a bank. Even if they’re open, the airport exchange desks offer unfavourable rates. If you do bring dollars cash into Vietnam, make sure they are not badly tattered as they may be refused.
