We have planned to travel from Siena to Assisi on April 25. It is a National Holiday. We have two questions. As of the schedule in January there is only one bus from Seina to Assisi listed in the late afternoon. We have heard that there is also a bus mid-morning at times. Do you know when they add the second bus to their schedule (Sena or Balfour Bus)? Will the buses run on the same schedule on April 25? If not, I may have to change when we leave Siena. Thank you all.
