I would not worry about the small well covered toilet in the Viewliner. Toilets have been in roomettes, slumbercoaches and duplex sleepers since the 1940's. If you need to go in the middle of the night you will appreciate the convenience. Most of the time its just for a piddle so its no big deal even if your wife or husband are in there with you. I would assume that your spouse has seen you in the buff before so if they get a peak you won't die from it. Most of the time they will be sleeping anyway and their head will be on the other side of the roomette. If you are very modest and your partner is awake just ask them to pull the covers over their head for a moment. Now if your event has a smell associated with it, then that's vacate time.
