The lawsuit does basically say that.
I also am not sure what type of accommodation could be given to help with pain in getting on or off attractions. If you have one, and it is reasonable, you can discuss it with a Guest Relations. I think one of the issues is there is really no accommodation.
We ran into that with my father in law, who had very bad hips and knees. What he finally concluded did help (after fighting it for many years) was an
ECV so that he could sit when he needed to and park it when he needed to walk.
A cane would have helped some with getting on and off some attractions, but he never agreed to that.
Many people have said that standing still hurts, but there are many attractions where there is no way to avoid standing still for varying time periods.
Many of those are attractions that load in batches or shows, so DAS would not help.
Places to wait near the boarding area might.
I was the person who mentioned seeing more wheelchairs and
ECVs.
That is not a recent development. We have been traveling to WDW with someone using a wheelchair since 1987, and saw a steady increase of devices during that time, so it doesn't have anything to do with DAS.
In the last 3 years, we have seen maybe a few less ECVs and a steady increase in the number of guests using rollators (wheeled walkers with fold down seats).
For se guests, those are s very good device - a seat when you need it, walking, easy to fold for bus or car.
