Hi I’m travelling with my partner and our 2 kids from stockholm to lulea and back by nigth train.

Is it possible to reserve a full 6 compartment (meaning 2 beds “left free”) ? for how much is it possible if we have a 4 days pass ? I know it’s possible to reserve a full 2nd class 6 beds compartment on the SJ website for a price, but not sure with interrail.

Thanks a lot for any answer !
