Hi all. Is Bedroom B on car 531 upstairs? I have never traveled on Amtrak and am unfamiliar with the layout. My mother has some trouble with stairs, she can use them but it will be a bit slow. I know the sightseeing car is upstairs, is the dining car upstairs as well? Can you travel between the cars upstairs? Or would we need to go downstairs from our bedroom, then cross to another car, then back up the stairs to get to the sightseeing or dining car? Or if we are in an upstairs room could we stay upstairs to cross cars? Do they have bedrooms on the bottom? If so, I can call Amtrak and see if they can switch us to a lower bedroom. I know that was a lot of question, so I appreciate any insight you can give. Very excited for my first trip.
