Thank you for your response
Of course, I searched and found a lot of information on the Interail website.
This route is available 60d in advance.
I’m in France and we’re traveling as a group and we need 7 reservations.
Booking is not possible on Dbahn.
Booking is possible on PKP but I don’t know how to get reservations for 7 people.
The reservation of this same train for the week of 15/08 was possible last week but this week, it no longer works.
Yesterday, Interail indicated that the reservation was no longer possible.
Now that has changed, he says: “Prices temporarily unavailable Check back in a few hours to see prices and book this seat reservation”
Thank you
