I don't know about the guest assistance pass.  However, you can get online at Disney's offical website and print and order maps of each park.  http://disneyworld.disney.go.com/maps/ - DizneyGirl  382.1 #10 9:25PM

I went with a person in a wheelchair. There were some park areas that had special entrances for them and yet most of all the parks had lines that could handle a wheelchair. If the issue is something else, I'm sure you could call and ask for more details. You will have so much fun, but be prepared that it's much more physically demanding. You can't just pop over a few steps to the next park.:) - ally  445.0 #4 9:29PM
