I will be arriving in Rome airport and taking the train direct to Florence. Have confirmed train schedule and lots of trips available. Question on buying ticket in advance for a specific train and then missing it due to a late flight arrival. Does anyone know if the ticket could then be used/exchanged for a later train on the same day? I can't recall the rules...
Also I'm assuming that the Rome Termini station to airport service is a recommended way to get back to the airport and avoid higher priced taxis and traffic?
