What is better to bring, travelers checks or dollars and is it easy to change them?
You can exchange dollars and travelers checks at any bank or exchange service and there are even banks in the airport. The banks that will exchange money will have the rates posted outside. They all have basically the same rates and comissions. Some have no comissions but I imagine it is because they give you a lesser rate. Anyway it is not much and it really does not matter where you change your money or whether it is in dollars or travelers checks. I usually bring a credit card for emergencies and there are ATM machines all over Athens and on most (if not all) the islands. Most people use the ATM machines now. They feel that if you use a travelers check you get hit in both directions, buying and selling.
