Hi all we are off to Vietnam in three weeks struggling to find out how much spending money we need for 2 weeks for four of us, everything online seems to be aimed at US travellers. We have all hotels booked. Need to cover two meals a day for four (breakfast included in our hotels), excursions like lantern making, cookery class, and trains/buses between stops with the odd private driver. Street food ok for lunch and mid priced dinner places. I would like to take some cash and then transfer what we need to a Wise card so not paying transaction costs on my bank's debit or credit card. Thanks in advance
