A trip to Europe is not cheap but it is well worth it. Things are generally more expensive in Europe. You will need both cash and credit card in Europe but remember that charges and fees will be high. Navigating through Europe is kinda off difficult so you will need a GPS device, an old-school map and a compass. Believe me you will need a compass to orient your self from time to times so you do not get lost too far especially in Rome. Hope this helps someone!
