One more perpendicular person here. The side-to-side rocking in a roomette makes me feel like I am falling out of the bed; I have to either sleep leaning against the outside wall of the car, or make a pile of pillows/luggage between myself and the inside wall of the roomette. I'd happily try a duplex roomette style accommodation - though I would miss the daytime config of the roomette.
Maybe there is some clever way, with one person's feet under the next person's chair, to have daytime facing-forward seat and nighttime perpendicular bed in the same roomette.
