We are planning an 11 day trip to Italy in October, split between Rome and various towns in Umbria. For Rome we obviously do not want a car. But for six days in and around Umbria, should I
a) go back to FCO airport to rent a car and drive to Umbria and return it to FCO for our return flight home.
b) rent a car at Rome Termini station, drive north for our Umbria travel and return car either to Termini or FCO
c) take the train north (Orvieto perhaps?) rent the car there and return it there and take train out to FCO
Just wondering what might be best car rental option.
