When I travelled on the Canadian last month, a Cabin for One was originally $1200 but by the time I went to make a reservation it had dropped to $800. So I splurged!.....For the $1200 I was going to spend anyway…..I could now have single occupancy of a Cabin for Two. Certainly more room and the private toilet is in a small annex so at night you don’t have to raise the bed. I ended-up with my room being in Car 39.....the Park Car!
It was more comfortable for a four-night trip, but I’ve travelled in a Cabin for One for years and they’re just fine also! It’s personal preference.
The Cabin for One (Duplex Roomette) in the link below is the type you would find in a “Chateau” Sleeper. Those in a “Manor” Sleeper usually found on the Canadian are slightly larger and all on one level….not step-up.
The Cabin for Two (Bedroom) in the link below are the same as shown. The Manors also have a slightly larger Cabin for Two and it’s shown on the floorplan as a Compartment (but sold by VIA as a Cabin for Two also). And you could really splurge and get a “Cabin for Three” the old style “Drawing Room”
