I’m trying to make seat reservations with both me (Interrail pass holder) and my parents (Eurail pass holders). I've duplicated my trip and added them both as travellers, but when I proceed to make seat reservations with all 3 of us, I am unable. An exclamation mark appears in the area under “price.” Is there any way to circumvent this issue, and make reservations for us 3 together online?
Thanks for any insights!
