If she requires use of a wheelchair or scooter for the parks, she and her party can use the disabled seating section. I just returned today from a trip with my parents who are 69 and my mom has had a stroke and can't walk/stand very long and has to use a scooter. She was able to sit on a bench in the blue disabled section and the rest of us (6 others) sat with her on the bench or stood behind her during the show. Take a blanket or beach towel to sit on behind the bench while you wait and then stand during the show. There were several elderly people using those benches for the show. Obviously, the benches are for the actually disabled people, but if they don't fill up, the CMs let companions sit there as well. At least that's what happened for us the other night. If the benches fill up, you can at least stay in that section with her and stand behind her.
