We will be in Florence and need to travel to Siena on Saturday, then return to Florence two weeks later. Do you have info about frequency and times for bus to and from Siena.
FYI: The buses park around the corner and across the street from the Florence train station. Just look for McDonalds, and they're to the right of it.
Very frequent service. sitabus.it/sita-toscana/Firenze-Siena2010.pdf
Are we thinking about the same bus station? Here's a link to the station where I got the SITA bus to Siena. I don't recall a Mcdonald's there. I think that's a different bus company (Lazzi?) Anyway I took SITA from their main station in Florence to Siena. http://www.casa-al-sole.eu/Hauptbahnhof%20Florenz%20zum%20Busbahnhof%20SITA_e.pdf
