I have a similar question as the post about a purchase from Bahn.de -- I purchased 4 couchette tickets for my husband and I and the couple we are traveling with. I purchased the tickets at the same time so that we could all be in one couchette together and not share with others -- the ticket says:
ZUG 40388 CNL Wagen 290 Liegeplatze 71 72 75 76
I know that the beginning part is telling me the train & car #. It also says, elsewhere, that we have 2 above and 2 below. The part that concerns me is that the rest says 'Berths 71, 72, 75, & 76" -- can anyone tell me if these 4 berths would be in one room or if somehow we got separated?? I tried contacting Bahn with these questions, but got no response.
