This September we will be flying into Rome (FCO) from Chicago and have decided to pick up our rental car at the airport and drive to Parma. (We have reservations for two nights at Antica Corte Pallavicina and they are sold out for the rest of the week, so making the trip to Parma that day is a decision we've made). So dear posters, what is the best route to take? Google Maps shows the A1 as the first choice but there is an alternate up the coast. We are looking for the least stressful, most efficient way to get there. I have been assuming the A1 route would be that, but would appreciate hearing from you.
