Hi! Sorry for my very dumb question in advance. I’m going interrailing this summer for the first time and was wondering how do I book tickets to trains that don’t require seat reservations? I was looking via the interrail.eu site, and it wouldn’t allow me to book them, just showed that no reservation was necessary. Do I not get a ticket and just show my interrail pass on the train?

Thank you in advance if anyone can help me with this!
