Will be staying in Florence and doing a day trip without access to an automobile. How do I get from Florence to Capalbio/Tarot Gardens, then onto Siena, then back to Florence in one day via public transp? Alternatively going from Florence to Siena and then Siena to Capalbio and then back to Florence? I have never traveled to Italy before and speak very little Italian. Would appreciate any information I can get in advance of my trip. Thank you.
