My grown daughters and I are planning to drive from Rome to Tuscany and on to Venice. I've read about the difficulties of driving in Rome and am hesitant to attempt it. Is there a rental pick up spot close to the city border or would you recommend going to the airport for pick up? We'll be dropping the car in Venice. I'm the only one with an international driving permit and I don't want to be responsible for the three of us ending up in the hospital or in jail! Thank you very much for your help.
