Italy is a member of the European Union, and the currency is the Euro. The south of Italy is supposed to be less expensive than the north, but it depends on where you go in Sicily. To exchange money use an exchange office where you see the sign cambio, as their service is far simpler than that of a bank. They are quicker although they do take a substantial percentage. An ATM, called Bancomat is the easiest way to obtain currency with your credit card. Make sure that you always have enough cash. Sometimes the ATMs in Cefalu get empty, for example on Saturdays, and new money is not provided before Monday. In most restaurants and shops credit cards are accepted, but this can vary and we recommend you to always check first if you wish to pay with a credit card.
