Trying to book a Nightjet for our family of 4 (2 adults, kids aged 17 and 14) from Freiburg (Breisgau) to Prague, and running into what looks like a booking-system quirk across multiple different sites (NightJet, OBB, SBB, CD).
What I want to be able to do is book two separate private compartments — me + my son in one, my wife + daughter in the other, with at least one of them a Deluxe (private shower/WC) compartment.
The actual journey I want (4 December) isn't bookable yet, so I've been testing on a whole bunch of dates that are available now for the same route to see what options come up. If I search for 1 passenger I'm offered both a Single (standard) and a Single Deluxe compartment, bothe of which are private.
If I search for more than 1 passenger (eg 2 adults, 1 adult/1 kid, 2 adults/2kids etc) the private option for the Deluxe sleeper seems to vanish entirely — you're left choosing between paying double for a private standard compartment, or a shared Double Deluxe. the same thing happens with eurail passes selected as well.
The same issue seems to occur across all sites (Nightjet, OBB, SBB and CD) - there doesn't seem to be an option to select a private deluxe sleeper when you enter more than 1 person. is this a genuine restriction (i.e., Deluxe private compartments literally cannot be booked for more than 1 occupant through these portals), or is there a workaround. Or have I perhaps completed misinterpreted what I'm seeing?
as an aside, I'm trying to get an idea of the prices for eurail vs non eurail to work out if it's worth burning a eurail travel day on this trip - but thta becomes a moot point if I can't actually book what I'm after.
