We would love to take a day-trip from our lodging in Siena to Montepulciano in April, and Sunday makes the most sense given other activities we have scheduled. I would prefer to simply rent a car ---but of course there are no rental agencies open in Siena on Sundays. I saw that there is a timely train service between the 2 cities----but then I discovered from past Forum posts that the Montepulciano train station is some 5 miles form the old town! Those past posts mentioned that a bus runs between the train station and the town, but I cannot locate a website or other information to see if the bus runs on Sundays and what the schedule might be. Could someone please direct me to the bus schedule website? Any other advice on getting from Siena to Montepulciano would also be appreciated. Thanks in advance!
