Freemore,
I use to push my mother in her wheelchair before she got her powerchair. There is no elevator at the MK monorail stations and to us it's steep. There's no one to help push you up the ramp/path, but once on top they do help with loading you on. Once we arrived at the MK entrance , I would wait for everyone to reach the bottom of the ramp before we started down because once you start going down it's hard to stop. That's how steep it is. I didn't want to run over any kids or people's heals. I've complained. I was told to take the boat. If you take the boat you have to go backwards down their ramp. You will see signs showing you how. There are people at the boat ramp to director you, but they can't push you. If the water level is low, you must take the monorail.
Epcot has an elevator at their monorail station. MGM doesn't have a monorail. Disney's busses are wheelchair accessible.
