I bought an Interrail Pass a couple of days ago and after that I booked the mandatory reservation for the Eurostar to London. Now I would like to exchange my Interrail Pass (from 4 days to 5 days). My question is: Will my Eurostar reservation still be valid for the new Interrail Pass although I had to enter the pass number during the reservation process and the new Interrail Pass will have a different pass number? (I am talking about the Interrail pass number, not my passport number!) My new Interrail Pass will of course be valid on the day I made the reservation for and it will still be a Global Pass, 2nd class, like the previous one.
Thanks for your help.
