I had bought a Global pass and made a Eurostar reservation for April 8th for 32 Euros.
I have now decided to travel without an Interrail Pass as I will be making only a few journeys and I hve already received a refund. However I would still like to travel on the Eurostar train that I booked. So am I able to use the Eurostar reservation I made? Pay the difference somehow? It will be about £65 Thank you
