We are planning a trip to Italy. We plan to fly into Florence, spend 2 nights in the city and then wish to travel to some outlying areas to explore the country side and wineries. We then plan to travel to Amalfi coast for 3 days and finally to Rome; where we will depart. we are looking for suggestions for travel. We were thinking of renting a car after Florence and keeping it until we end in Rome, Does this sound reasonable and where is the best place to rent a vehicle?
