Lourdes, thank you so much for your reply. As luck would have it, our plans have completely changed because our accommodation has apparently severed their relationship with the time share exchange company. So I've cancelled the rental car and found a reasonably-priced hotel in Florence. So now it looks like my daughter and I will be spending most of the week in Florence, and taking public transportation for any forays into the countryside or other towns. I'm a bit disappointed because I was looking forward to the adventure of driving through Tuscany!
I do have another question--without a rental car, what is the best way to get from the airport to the train station area?
Thanks in advance!
