I would be disappointed but I have to say, I may be one of the reasons someone else maybe downgraded, so I thought I would share to let others know why a downgrade may happen. This was back in the days that Disney did not accommodate blind and before a device called trekker came out.
I am legally blind, my dd has cerebral palsy, my other dd has something between the lines of aspergers and BiPolor, and grand d was a preemie baby. When DD's were teens and grand was baby under two this happened several times.
Once in wdw we were at POR, it started pouring out and we headed back. Once I stepped on the bus and had the carriage the teens got back on bus and took off. Here I was with a preemie who was maybe a year old so looked a lot smaller, and myself with carriage and bags and cane. Trying to find my way back to the mansions. I made it over to the mansion, but could not find a way up with carriage and cane up stairs to find the elevator. Finally after what seemed like hours and a lot of swearing, a guest helped me back to the main office, they changed my room to what I now know is a preferred room,the closet of all the rooms to the food court and bus in building 14. It never dawned on me then that I may have taken a room away from someone else and they never told me or charged me any extra.
Yes you can blame my kids, but they were like 15 and 17 a little immature and thought why not go back to the park.
On two occassions I was upgraded at DL, both times I think it was due to my visual impairment. The first time was when they had to close one building, the main one had electrical problems so they were trying to get everyone to other rooms and we were not checked in but I got a call, they could not give my request to have two different rooms in two different buildings, we were traveling with ex husband and sometimes we need not to be right on top of each other. Since one room was for the blind with a request in dream, and the other was a request for an acess able room, my ex is a vet with a cane. The only way they could accommodate us was to put us in concierge, would that be okay. I told them yes but not sure we could afford both rooms at a higher price and we were due in in 2 hours, he told us it would be free to us, or he could place us in two standard rooms at the grand but they would be connecting. We took the rooms at the grand this time, I doubt we kicked anyone out they were standard rooms but and it was not a busy time.
Another time was at DL when trekker first came out. When they knew I would be using one and asked them if someone would give me a tour to get it set up, they were excited and worked with me very well. They upgraded me, but I also gave them the knowledge of the new system and how it worked. A trekker is a GPS system that blind people can use. Once set in, it will tell me to walk, 10 ft to elevator, twenty ft to door, three ft to pool gate, I just tell it were I want to go. So I got upgraded and Disney got a CM with knowledge of trekker so they hopefully will be able to help the next guest who is blind. Again I doubt I kicked anyone out this time, they had knowledge before hand I was coming.
