We will be returning a car at the Hertz office in downtown Arezzo on Saturday Oct. 4, 2014 . Will there be any problems driving in to Arezzo to return the car on a Saturday? From there we need to get a train to Rome (termini). I checked the Trenitalia site and it looks like there are (3) Arezzo station options, Casello, Pesciola, and S. Giuliano D'Arezzo, which is the best for us to use? I assume we will need to take a taxi to get to the station - or could we walk? Can this ticket be purchased ahead of time or should we just wait until we get there?
