Hi!
I won a discovereu interrailing pass and i’m planning on travelling in august. My friend, who i’m travelling with, bought a 7 day in a month interrailing card since it’s the same that i received. We are now trying to book seat reservations but it won’t work. I’m trying to book everything togheter, since we want the same things and want to sit togheter. But when i try to add a traveller i get this message. What can i do?
