We were planning to take the train from Rome to Orvieto. Spending 1/2 day in Orvieto, then renting a car and driving to our next location near Siena. Unfortunately our scheduled date is 4/25, which is Liberation Day, so the smaller car rental places are closed, including Orvieto's. So we are planning to rent a car at the FCO Rome Airport and drive to Orvieto. We're concerned about driving in Rome. I see 2 routes - 1 is more direct - SS4-SS3.. but goes around the city, the other goes up the coast, SS1, but is 30 minutes longer. Any suggestions or comments about taking the longer route? Is it worth seeing and/or an easier drive?
Your thoughts and opinions are very much appreciated.
