We want to travel from Rotterdam to Bucharest, starting on July 15. Two adults and a child of 7 years old. We would like to take at least 1 nighttrain. We can travel via Berlin or via Vienna, both seem fine.
However, anyway we look, we can only seem to make seat reservations in nighttrains. Both here on interrail, as for example with Deutsche Bahn or OBB. We really want to be able to sleep in these nightyets. That was part of the reason why we want to travel by train.

Can anyone give us advice on what to do? Thanks in advance!
