Hey,
I am going to be starting my travel from Bologna/Italy. I was wondering if booking reservations for each train is a must. For example, If I were to go to Florence from Bologna which takes 25mins, would it be okay not to book a reservation? Or do I need to buy 1 for sure?
Also, when I go on interrail’s app, it says for most of the train tickets, I must book a reservation. How can I know when I need to book a reservation? Can I just not get 1 for short trips?
