Spain is part of the Euro zone. This zone is comprised of the following countries: Spain, France, Germany, Portugal, Italy, Greece, Belgium, Luxemburg, Holland, Austria, and Finland. These countries share a single currency, which helps to facilitate free movement.
Generally, traveler’s checks can be exchanged in any bank, although you may have to be prepared to go to certain specific offices or branches of each bank.
Ultimately, it is much easier to use a credit card, though beware the very high bank fees per transaction. Visa, American Express, Mastercard, and Diner’s Club cards are accepted in most commercial establishments.
Major cities have private exchange offices which change cash and, in some cases, traveler’s checks. These offices usually charge a commission for the transaction.
