My friends and I booked 4 second class passes. We wanted to travel through Italy, so we had to reserve seats for those trains in Italy. We decided to do this via Interail. However, they sent us reservations for first class.
So now we want to cancel the second class passes and book 4 first class passes, because there are no second class seats available on any other website. Our question is: can we still use the first class seat reservations we received with our new, first class passes, or are those reservations linked to our second class passes, because we booked those seats via our second class passes on Interrail?
