Credit Card Acceptance in Europe

In response to a recent question about credit card acceptance in Europe, I went back through my Quicken transactions and came up with the following statistics for the number of restaurants, stores, museums, churches, attractions or service providers that accepted (or were willing to accept) credit cards over our recent 25 days in the Mediterranean:

3 of 17 museums, churches or attraction (Vatican Museums, Basilica di Santa Croce in Firenze and the Time Elevator in Roma!)
6 of 15 vendors or shops (low because this includes street vendors)
2 of 4 tour companies (5 tours total)
0 of 22 taxi drivers or transfer companies
0 of 4 train, tram or cable car tickets
12 of 21 restaurants (lunch and dinner only, and does not include gelati places)

In purely dollar terms, if you exclude the cruise and hotel portions of the trip (the two most expensive items), credit cards were only accepted for less than a third of all our expenses.

As you can see, credit card acceptance definitely lags in Europe and around the Mediterranean so you'd better have lots of cash!
