I added an outbound journey from my COR to my pass, this was for London to Brussels.
when I arrived to get on the eurostar, they said I could not board as I did not reserve a seat.
Interrail app did not suggest I needed a reservation for this train time.
I have now had to book onto another outbound journey tomorrow, but it will use up 2/2 outbound inbound journeys.
What am I to do when I need to return to my COR at the end of my trip?
