Ok... So I am not having a car in Florence and want to go to Bologna for a day... I went on the rail site and still not sure if we need to book ahead? Does it cost a ton more to do last minute?
I have booked ahead on fast trains before, but this is such a short trip I am not sure. I want to be flexible due to weather and scheduling...
I did the train to Sienna and don't remember booking ahead, but maybe I ended up paying more... I will have some other people with me, so don't want to give them the wrong advice:)
