You actually do more walking when using the AAA spaces. They are best used if you are staying for the parade/fireworks and are exiting when the rest of the world is. You still stand in line to get on the monorail, but you won't have to wait a second time for the parking lot shuttle---just start hoofing it. The parking is to the side of handicapped parking, so you walk through that entire lot and down the path under the tunnel and around and finally end up at the shuttle stop. When going for just a few hours during the day it's really easier to do regular parking IMO.
