We are landing at Fiumicino airport on Wednesday, March 13, and need to travel to Orvieto for our first night of the trip. I find it difficult to use Italy's train site, www.trenitalia.com. I believe that we will need to take a train from the airport to Rome's Termini station and then change trains to get to Orvieto. We land near 7 AM on a Wednesday, March 13. Can anyone help with the train schedule from Fiumicino to Orvieto? Can the tickets be purchased from a machine? Any advice would be much appreciated.
