Just curious.... We will be taking the train (not booked yet) from Lucca to Rome Termini station in late April. I know we have to change trains in Florence. Is it best to stay with Trenitalia trains on the Florence to Rome portion, since that is what is used on the Lucca to Florence segment; or would it be no problem changing to the Italo Trena trains on the Florence to Rome segment? Just starting to look at the schedules, prices, etc. (but I don't think we can book for 2 more months due to our travel dates). The connection times look to be about 14 minutes, depending on what time we leave during the day. I wasn't sure if staying with Trenitalia we may have less distance walk to get to the next train as opposed to changing to Italo Trena. And if for some reason our train from Lucca departs late and we miss the connection, I would assume that if we stay on Trenitalia we could get the next train, even if booking in advance? I appreciate any thoughts and/or experiences. Thank you.
