For those that have difficulty walking, I agree an
ECV of wheelchair is the most appropriate however, there are those that have difficulty with standing, say in a queue, but also have difficulty with sitting for extended periods of time. The response is get a wheelchair or ECV, well, if they can' sit for long periods of time, then these are out and don't give me that they can push an empty wheelchair around the park and sit when they need to. Which back when this was the case for me I did and security would stop me about every 5 minutes to ask why I was pushing an empty wheelchair, not to mention it is very difficult to push a wheelchair when it is completely empty, as it wants to keep doing wheelies and then trying to maneuver around other guests is even more difficult than when someone is in the wheelchair. Now if there is more than one person in the party and the person with the needs is pohysically able to push the other person, that can work. But often they aren't physically capable of it, so that doesn't work.
I am not saying that a wheelchair or ECV isn't ever appropriate, but I am saying that about 20% of people that have issues with standing may not be able to utilize an ECV or Wheelchair and that they need to be accommdated as well, so please let' not just automatically blanket people with standing issues as mobility issues and Disney does need to do a better job at addressing this issue, but I also think those in this circumstance need to be able to find a way to better articulate why and ECV or Wheelchair won't work in their particular case.
