Hi,
Arriving in Rome on a Saturday morning at 8:30AM in late-September. Need a train from Rome to Florence upon arrival. Would prefer high speed rail. Best to buy tickets in advance or when we arrive? Not really concerned about small, incremental savings. Only concerned about availability of last-minute seats on high speed trains and the possibility of needing to change reserved tickets if flight is delayed or if arrival at FCO is delayed by immigration/customs/etc.
Thank You,
Ben
