Dears,
I want to make Seat reservation for the night train IC 390 which goes from Hamburg to copenhagen on 23 June 2023. (23:56 to 7:03)
I tried using DSB and DB sites, both say that reservation is not possible, while Eurail site says that no seat reservation is required.
Could you please let me know if there is a possibility to make the reservation or not.
Thank you
