This may or may not be helpful, but a friend of mine's mother joined them on their most recent family trip to WDW, and he was worried that she may not be able to enjoy her time as she didn't like rides that moved fast, had long drops, etc. But she actually had a blast!
Her favorites at MK were IASW, Peter Pan, Philharmagic, Haunted Mansion, Carousel of Progress, and Jungle Cruise. At AK, she loved Festival of the Lion King and Kilaminjaro Safaris.
I believe she skipped the day at DHS. As for Epcot, she rode Spaceship Earth and ate and shopped her way around while the kids did Soarin', Test Track and Mission: Space!
Truthfully, when she was telling me about her afternoon around Epcot, I was a little jealous.
