I have Amex SPG, Delta, AAdvantage business & personal, Costco; Visa - onepass, chase freedom; MasterCard - Citi PPE, Sony I didn't have much time to call & research each card to know if there are any additional fee for each transactions? I probably will be using at hotels, restaurants, siteseeing centers, tickets, trains, etc. This is my first time in Italy and for tourism. If all the cards charge any fee, which is a better card (for knowledge sake)? Also, how much cash/travellers cheque should I carry for 7 day trip approximately? Other form of mode of payment any recommendation?
