Public restroom visits were the absolute worse. My mom doesn't like them to begin with, but the frequency needed at the parks makes it even more horrible. I kept her on a schedule to avoid accidents. That strategy worked very well but she had bad outbursts including screaming and swearing in them. Some places were tight fits and that made it even worse. On one occasion, there was a knock on our stall and it was a nurse asking if she could help. I knew that would be worse for my mom; so, I declined the offer. I explained she has Alzheimer's and I could handle it it but it would take a little time to clean her, etc. She understood. That episode must have been pretty bad, if I was approached by a stranger. I try to tell my mom not to scream, etc. and sometimes that can made the situation worse. I didn't want children in there to have the Disney Magic get ruined; so, I tried my best, but there were more bad times than good in this regard. Thank goodness she doesn't want to take her sweet time in a public restroom; so, it was short episodes there rather than long ones. When I could use a companion restroom that was the best. In Epcot, I loved the companion restroom in Germany and The Living Seas; because, they were somewhat separated from the common area. I wish there were more of those throughout all the parks. Fortunately, she didn't have any really bad outbursts out in the public areas on rides, shows, etc. I would have probably been scared if she did.
The other bad situation was my mom refusing to wear her coat during one of our private photo sessions at the Wilderness Lodge. We had jackets on, but she refused over and over again to wear one herself. I believed she got chilled on that occasion; because, most of these sessions are outside. Well, she did get sick and our last morning there was spent at a clinic. She had a bad sinus infection (like a head cold) and she was given an antibiotic. Her throat was red per the doctor. She was given 10 days of meds and she is still on them, now. She is very irritable about it. She never liked colds (who does?) and she can be nasty with them.
I will admit that Once is Enough for this experience with her. I think the trip was a little long for the circumstances. The other side was that we needed the length to see all we could see at all the parks; because, I knew I wouldn't do it again. If I was local; I would scale back. She did become disoriented, especially when we switched resorts with our layover nights coming and going there. I'm planning for a Dollywood trip in Pigeon Forge for next Christmas season, now. There are a lot of shows we can see there; so, I think that will suit us. We can get a resonable condo there and we can have a shorter trip. We will be able to drive there in one shot which is a good bonus.
Would I do it again knowing what I know now? That answer is an absolute yes! There were a lot more positive aspects to the trip than negative ones. Good luck to all that try in this regard. I would say it's doable, as long as, you realize every moment will not be perfect. If I can be of any help to anyone with any advice let me know. You can private message me here, as well.
Thanks to all for listening and supporting me in my efforts to accomplish this trip with my mom.
I fell sorry for you!
