One more question. Considering a handicap room, accessible as it's labeled. What are the pros and cons of being in an accessible room as opposed to a bedroom? I know there's not a shower in the accessible room, but what might make it better, or not?
As you can see by the specs posted above, both beds are narrower in the Accessible Room: the upper by a few inches, the lower more significantly. You can squeeze two skinny people into the lower berth in the regular bedroom, but not in the Accessible.
Also, while the Accessible has windows on both sides of the train, they are half as wide as the windows in the regular bedroom or roomette, so not as panoramic of a view. And of course they are much closer to the ground, which also reduces the view. The regular bedrooms only have an outside window on one side, but they also have a windows onto the corridor, and there are outside windows all along the corridor, so you can see out the other side to an extent when your privacy curtain is open.
The one time I occupied a Superliner Accessible bedroom, there was a problem with sewage smells; not continuously, but maybe for an hour or so from time to time. There was also a problem with the doors on the adjacent public restrooms banging throughout the night, as people using them failed to close them completely after exiting.
Overall, unless you need the wheelchair access or can't negotiate the stairs and plan to stay in your room the entire trip, IMHO a regular bedroom is far superior to the Accessible room on a Superliner. Now the Viewliner I Accessible rooms don't have all those issues (maybe narrower beds, I'm not sure about that). I haven't experienced a Viewliner II Accessible room yet.
