Having read many archives about paying for train tickets in Italy, I am now confused about buying a ticket and/or having a seat reservation on some or all routes.
I will be travelling from Pisa to Florence. Then Florence to Rome, then Rome to Naples. (not all on the same day!). I intend to use the automated machines to purchase tickets. However, I am confused as to whether I also need to purchase a seat reservation in addition to a train ticket? I think maybe some routes you HAVE to have reserved seat and other you don't I'm not fussed as its early June we travel, not 'peak season'
So can anyone tell me if I need to reserve a seat also and how I go about it if using the automated ticket machines?
