my mom is ok with taking her foot off, but my mom is not keen on peter pan anyways so thats a ride she wont be doing lol thanks for the input. yea my mom just ordered one of those walkers that has a seat attached so that should help some as well

and I am sorry for your friend hope she is doing good
We saw a lot of those walkers on our recent trip. They seem to work very well.
With the walker, she will be able to use whatever is the wheelchair accessible path/boarding area for the attraction without having a Guest Assistance Card.
Check out post #3 of the disABILITIES FAQs thread. Near the top of that thread, there are links to the Guidebooks for Guests with Disabilities for each park. In general, the Studio and AK have all Mainstream lines (which means they are wheelchair/handicapped accessible). Epcot is mostly Mainstream, but has a few attractions with other access routes (Spaceship Earth is one). MK has a mixture of Mainstream and other access. The Guidebooks will tell you where to go - either "Enter thru the Mainstream Queue" or it will tell you where to enter. Besides this electronic version, you can pick up a copy of the Guidebooks at Guest Relations in any park.
If you get to an attraction and the CM is not allowing you to enter at what you think is the correct access point, check the book. In most cases, the line is Mainstream and there is no special access point.
Also in post #3 of the disABILITIES FAQs thread, there is a post about boarding rides, specifically those with moving walkways. The link is toward the top of the post, before the alphabetical "conditions" part.
ALSO - CLARIFICATION ABOUT PETER PAN
Your legs don't dangle. The Pirate ship you are riding in does have a floor. Once you have entered the boat and the ride starts, your boat will be dangling (you are flying, after all).
The information about the moving walkway is correct though. It can't be stopped on Peter Pan (except in an emergency). The time and space you have to board - and especially the time and space to get off - is limited.
The last time we rode, my DH almost ran out of moving walkway while he was carrying DD off the attraction.
