I think we have narrowed down our September 2017 trip. If our (4 adults) itinerary looks like this
Florence - 3 nights ( we fly into Florence so really only 2 1/2 days) - If we plan to take a day trip to Siena from Florence - can/should we take a train
Bologna - 3 nights - If we plan to visit Parma from Bologna - can we take a train. I know one day we are planning to take the Italian Days Food Tour so we don't need a car for that.
Lake Como or Lake Garda (a coin toss right now) - 3 nights
Getting from Bologna to Lake Como - can we take a train or will it take too long
We rented a car in Italy on our past trip and found it easy enough to get around and followed all the no parking zone laws. We drove to Siena last time. We stayed a week in a small town in Tuscany and drove everywhere except to Florence when we took the train and it was ok going there but coming back - geez - not a good train story. Some travelers are good with trains...I like to have a car but it seems for this trip it might be more a hassle to have a car.
