I have to travel a lot between Amsterdam and Brussels, and I have to travel quite early. Therefore, I would have to use the Eurostar. Using interrail would be the cheapest option by far.
My country of residence would be Belgium, my passport is Dutch. But you can only do one inbound and outbound train ride.
Do you think the person that checks the tickets would want proof of me not living in either of these countries after my first inbound and outbound trip, or would it be possible to say: “oh no I live in France at the moment!” - I have lived with a friend of mine in France for a bit, so I might have an address I could tell them.
Anyway, how much proof would they want and how illegal is it to just say I am staying with a friend of mine. I didn’t have proof of my residency in France at the time either.
