I'm hoping and guessing that trenitalia has not yet loaded all of the schedules and fares for the later part of summer 2016. For example, I need to book a ticket from Florence to Venice in the later evening of June 27, and although those times show up, the tickets cannot be booked. And on July 1, there are NO schedules or fares for Verona-Orvieto, although if I inquire about Verona-Bologna, then Bologna-Orvieto, there is one possibility (a slow one) available. I've been checking on these schedules for several weeks, but nothing new has loaded. Is it time to just cool our heels and wait for trenitalia to slowly fill in the schedule? Thanks for advice!
