Try to get an odd-numbered roomette, so you will have a room on each side of the train. I think you will especially want this if the bedrooms are on the inland side of the train.
When your parents sign for their meals, have them sign the meal chit indicating the room to which they are assigned, even if that's different from the room where they sleep (as it sounds like it is).
Enjoy the trip.
