We will be travelling in September to Florence and have 5 1/2 days (6 nights) to spend in Florence and will be spending 2 nights in Pienza. We are definitely going to Cinque Terra for one day (know its along day but are determined to see this area,) and one day taking a trip to Lucca. We also wanted to take a day trip to Volterra and San Gimignano. We thought we would visit Sienna on our way to Pienza or while we are in Pienza. We also plan on visiting Montepulciano and Montalcino while in Pienza. Any itinerary help would be appreciated. We were going to rent a car when leaving Florence, but maybe I should get the car the day before going to Pienza and visit Volterra and SG by auto. (Thoughts)?????
