We want to rent a car on our return from Venice. We leave Florence to Venice and we will depart Venice for Sienna. After Sienna we will depart from FCO. We have been told by your site and others about the difficulty of parking in Florence and Venice. We were thinking about the train from Rome to Florence; Florence to Venice and from Venice. 1--Where would you rent a car--Venice, Florence or Sienna? 2--Would you return it to FCO or drop it in Sienna and take a shuttle to FCO? 3--Do you need an EU driver's license to rent a car? 4--Are rentals in Italy manual as opposed to automatics? Thanks for your help.
