Two of us will be on a honeymoon in Tuscany in a few weeks. 1st time in Italy. We will be coming in to stay in Greve from Rome on a Saturday. We will be based in Greve for 3 nights. We will be leaving on the 3rd day for Lake Como. I am wondering since we plan to see the countryside and take a day-trip to Florence if it would be a good idea to take the train in from Rome to Siena, rent a car, then return it to Siena & hop on the train for Milan/Como area?
Thanks for your help in advance.
