We land in Rome Fiumicino at around 16:25 on 31st October and I over-optimistically (or was it the red wine?) booked a couple of tickets on the frecciarossa to Florence leaving at 18:10 from Roma Termini......doh! Thinking about it in the cold hard light of day, getting off the plane, getting through the airport checks, collecting hold luggage and boarding the Leonardo Express to get to Termini in just under two hours is silly. Is there any way I can rebook the tickets to a later time, or have I just lost $153 due to my own stupidity?
