We took my DMIL 93 to WDW for her first trip in June. While we were there she used her own wheelchair if we were going long distances as she can walk short distances but is too weak for anything over a 100 yards or so.
We were at La Hacienda late one night and she decided she wanted to walk into the restaurant so we parked her wheelchair outside. We exited the restaurant about 1/2 an hour or so after the end of Illuminations so we could walk slowly out of the park after the rush.
We went to get her chair and it was gone!
This was her chair, not a rental. It had her name all over it. We thought maybe the Disney people picked it up?
We look down toward where Future World and the countries meet and there is a boy about 12 years-old with his family playing with a wheelchair. Yup. DMILs. We went over and politely said to him that that was DMILs wheelchair to please get out of it.
The parents never said a word to us or the child.
You wonder whether those parents even look at their child. A boy that old is old enough to know better and if he isn't, the parents have not been doing their job.
This has not happened for a while, but when in line for attractions, we have had toddlers sit right down on DD's feet on her wheelchair footrests. Luckily, DD thinks it is pretty funny. Most of the parents were horrified and pulled the child up right away. Occasionally they don't.
Also, one of DD's wheelchairs used to have the thin wire spokes, like bicycle wheels. They are kind of fragile if pulled and someone can get their fingers hurt if they are in the wheel when it moves. Multiple times we had to tell children to get their fingers out of there (they usually tried to strum them). Most of the time, the parents just paid no attention.
My worst story is when we went to Lights, Motors, Action. There was a line of guests with wheelchairs and
ECVs waiting by the elevator to get upstairs when one woman on an
ECV came back down and said she was sent down because all of the spots were filled.
A CM directed her, us (next in line) and 2 other parties to follow to get to another seating area on ground level. As we went along in a line, the guy behind me in an ECV kept driving his ECV into me (I guess he didn't feel I was going fast enough). I turned around and looked the first few times, then turned around and asked him not to bump me again.
When we got to the seating area, they said there was one companion seat per wheelchair/ECV and the rest of us would have to sit in the row behind. The person ahead of us did that. DH sat with DD and I sat in the row behind.
Then they came to the guy who hit us and they refused to split up. So, their party sat together a child and the wife taking a seat each.
The man got off the
scooter and sat on the bench, which meant that the next wheelchair spot had no companion seat (actually 2 seats short).
The CM told them they could not use the whole bench, so the wife got onto the ECV (still not leaving enough room for a companion to sit).
As the wife sat on the ECV, she crossed her legs, put her feet up and rested one foot on DD's wheel. Then she started cleaning her fingernails and flicked the stuff from under her nails over toward DD.
DD doesn't like anyone touching her stuff and I would have thought she was justified if she had hit the woman!
Regarding Companion Restrooms, there is a link in post 3 of the disABILITIES FAQs thread that has all the locations, with a little more information about each. The EPCOT FAQs thread has all the locations for Epcot.
Do be aware though, that some people with disabilities take a long time in there, so you may have a longer wait than for just the regular bathroom.
Also, many of the families using them in MK and the Studio have been rather 'unmagical' to us, so there are some we don't use and just use First Aid.
