Can anybody definitively confirm that IC trains in Italy do or do not require reservations for pass users?
My experience a couple of months ago was my reservation was checked. Interrail planner says reservation required, but on here and Facebook several experienced contributors say they are optional.
Italiarail - Trenitalia’s official partner also says reservations are required.
I am always concerned that Newbies get the correct information as on board. It is no good saying “I thought...” or “ I was told by …...”, when they have the uniform and the rule book on their side.
