I will be arriving in Florence with my husband the first week in April. My sister and brother-in-law arrive on a Saturday morning. They will spend the day in Florence. We would like to get a driver to take us to Sienna. is it possible to stop in Chianti along the way? Is it best to spend the night in Sienna or return to Florence? If Chianti and Sienna are too much to do, is it better to take a train to Sienna? If yes, should we book in advance?
