I will be in Montecatini for a week in July. I have been before with tour groups, and I have visited Siena, San Gimgnano, parts of the Chianti region, Pisa, and, of course, Florence. This time I would like to travel to other parts of Tuscany. I will be alone, so I really didn't want to rent a car. Anyone have any suggestions as to where else to visit in Tuscany, and, more importantly, how to get there?
