hi there,
The place to change your cash is at an authorized money-exchange office, which are in
Caracas, Puerto La Cruz and Porlamar, but there may be just one or two in other large cities.
The most popular foreign currency is the US dollar as the exchange rate favors us. US dollars are normally accepted by tour operators as payment for tours, and hotels may also accept dollars.
Visa and MasterCard are the most useful credit cards in
Venezuela but be aware that the surcharge can be very high!
