AWESOME! Thanks fellas for the responses. I'm relaying the cellphone info to my wife. I know nothing of those things.

I already got my AAA drivers license
I got 500 euro
Might just buy a GPS for the trip and return it
Notified my credit cards I'm leaving
Need to call the bank
Passing through Bologna, will either stay the night or just eat lunch.
US currency would be a nice fall back, thanks for the tip.

What else?
