Four years ago, my mom and I were walking in the Epcot parking lot. It was later in the day and we were parked in the first available spots behind the handicap section sort of parallel with the animal care station. My mom was so excited to be going to ride Soaring (her first time in the parks in 15 years) that she was not paying attention and did a fabulous old lady summersault over a handicap parking barrier. Luckily, she is in really good shape for her age and just ended up with a giant gash on her knee.
I helped her hobble to the first available bench, and went into the pet center to see about a first aid kit. They did not have one, but called someone. By the time I walked back to the bench (think 3 minutes) a cast member already had found her and called someone. Within 5 minute she had 4 managers, a security guy, the parking lot cast member and a paramedic talking to her. She declined transport, and the paramedic cleaned up her cut (luckily it was just a big scrape).
They offered her a wheelchair for as long as she needed, she declined. I did take a couple extra giant band-aids from the paramedic (they may have been difficult to find) and some antibiotic ointment. Then one of the managers, who was talking to my husband (he was a few minutes behind us) and offered my mom some fast-passes. She literally hopped over to get them. It was funny as heck seeing a 65+ year old woman, hopping on one foot, with a giant band-aid on her other knee to get fast-passes for Soaring. They gave her a pin for her hopping efforts. After "her show" she put her shoe back on and we walked to into the park.
Disney did follow up with her, probably because my husband and the manager were discussing risk management (that is part of my husband's job). She just told them she was fine--she just ended up with a bruise that would have made any 13 year old boy jealous.
