I think I've read shorter novels than that OP. I admire any complaints agent with the patience to wade through all the irrelevant, extraneous........verbiage. And very glad the OP at least bolded the part where they actually started to get to the point, even though that was still buried in too much unnecessary detail.
Still not sure why she chose to post this on the Theme Parks board, instead of either the resort or disabilitiest board, where it belongs.
Given the OPs handicaps, she should have booked a HA room to start with, on her first visit to the Poly. The fact that the Poly was able to accommodate her was pure luck.
When problems arise with free amenities and services, Disney's usual response is simply to withdraw those options. Period. Given her complaints about the WL not being able to meet her needs, I think it likely that Disney will alter their practices. Specifically, that toilet seat risers and shower stools will likely no longer be available for regular rooms and guests will be directed to either book a HA room or rent their adaptive equipment from an off site agency.
On future stays, perhaps the OP will take one of those 2 routes to avoid the problems she encountered. Hopefully those free nights at the WL will be in a HA room.
