Most countries we travel in on tour operate on the currency of Euros (insert symbol here). The best way to get Euros is to bring a debit or credit card that doesn’t charge you to use it in Europe or has no ATM withdrawal fees. Use the ATM machine at the airport or any bank you see to get some cash out. Europe functions on a lot of cash transactions. Paying 1 euro for a latte with a credit card is annoying to most shop owners who have to pay a percentage to the bank if you use the machine. On the flip side, don’t bring a ton of american dollars to exchange. The fees are outrageous and if you get pick pocketed that money is gone forever. At least with an ATM card, the bank may help retrieve any fraud charges.
