A person said in another thread: You can easily buy these tickets ( Regionale) at the train station up to 7 days in advance.
Is it true? I understand that there is a 7-day limit for online purchase of regional trains. Does the same limit apply at the station? I'm hoping it is much longer than 7 days. I plan to buy all my regional train tickets needed throughout the 21-day trip (in May) on my first day in Italy (at Rome Termini). Does it work?
When I look for a train ticket from Florence to Vernazza, the online timetable gives an itinerary with a connection in La Spezia and with both legs on regional trains. When I make the actual purchase in Rome Termini, with the Departure set as Florence and the Arrival set as Vernazza, and select the above itinerary via La Spezia, will I be restricted to these two particular trains, or will I have some flexibility to travel on different REGIONAL trains, such as of a different time on the same day, or making the connection in Pisa instead of La Spezia, without having to stop by the ticket window for a ticket change?
Thank you for your help.
