Hi Andrew. Is your son going to study at the Academy of the Arts in Florence? My son is going to study there in the fall and he is also going to fly into Rome for the 1-week Introduction to Italian Culture class. I don't know if your son is in the same program but I was hoping that transportation from Rome to Florence would be included for the group.
My husband & I will be visiting our son for a few days at the end of September and then we are going to travel to Rome to begin a Globus "Best of Italy & France" tour. Our plan is to take the train from Florence to Rome. I have explored options and there are several trains per day and the fares seem reasonable.
I hope your son has a great trip!
