@Gail I'm coming from Florence. Flight scheduled to arrived at 9:15am on a Monday (in the fall).
Just thought might easier to walk to Tram T2 stop (close to the airport) which brings me to Florence SNM main station, then take the train (source: https://www.discovertuscany.com/siena/tourist-info/getting-to-siena-without-a-car.html)
The same link provide the instructions for bus 131R but it sounds hard to find. Have you or anyone else travelled this way? (Tram from Florence airport to Florence SNM station, then get to the bus station for bus to Siena.)

Is it easy to locate the ticket machines at the Siena bus station for ticket buying? Also where are the machines that validate the tickets? At the bus platforms?
Hmm I will have to see if there's a bus around 11 am onward for me to take. If not then it'll have to be the train.
Also I will have to take the bus from the Piazza del Sale to Siena train station when I have to travel to Lucca next.
Thanks
