Hello! A small group I am with and I all bought 1st class Eurail Global passes. Tomorrow, (we’ll actually today since it is almost 2am), we each got mobile tickets to travel from Nord Paris to London. It says that we need a seat reservation but every time I’ve tried to get one it says it’s not available and it could be from being sold out. If that is the case how am I able to have the ticket? When we go to scan our ticket will it not work? Or will we just not have a reserved seat? And if we aren’t going to be allowed to travel, what should I do? I hope this makes sense the way I’m explaining it. Also it said the seat reservation would be free since we were first class, I guess I’m just confused and nervous and not sure what to do. Please help, thank you :)
