I have a 10 day first class pass, not activated, and have already purchased through SBCB reservations for Eurostar and TGV.
I now wish to exchange the pass for one with fewer journeys and even though this is a reduction in value to Interrail I understand that I can do this for a 15 Euro fee.
Will my existing reservations (for which I had to generate a pass cover number) be valid with the new pass?
Thanks, Scott
