As far as I know, there are elevators, but not in plain view I think, I was there two years ago and I never saw them, but then again I had a ground level floor room (for the exact reason you have...my mother is horrible with stairs with arthritis and all

)
I mean, if you wanna make it easier for your mom and yourself, request the room anyways. Couldn't hurt, right? If not, then the elevators are there for you.
Watch, with my luck, there actually AREN'T any elevators, and I would be telling all of this to you for nothing. In any case, I apologize if I end up flat out lying to you.
But really, if all else fails, ask a CM on the phone. That's your best bet. That or one of the many people in this lovely establishment that would know much more than I would.
