These days, scooters aren't allowed inside Ellen's Energy Adventure. You have to park your
scooter outside and transfer to a wheelchair. Probably because of accidents like what happened to your child and the other one. It is pretty dark in the pre-ride area without worrying about scooters moving around.
MY WORST WDW MOMENT. I use a scooter and bring it with me to WDW. Last year DD, her BF, and I were at DHS and it was pouring buckets. We parked my scooter at RnR under some trees, and covered it with ponchos, and I transferred into a wheelchair for the ride. When we were done it was raining worse. We wanted to go to ToT, which also requires transfer to a wheelchair. So we just left my scooter covered up at RnR and DD pushed me towards ToT in the wheelchair. Since DD was pushing me, I was kind-of wrapped up like a mummy in my poncho. The street was all downhill, and all-of-a-sudden, I found myself free-wheeling and gathering speed. DD had lost her sandals in the downpour flowing down the street, and (not thinking) went back to get them, leaving me to fend for myself in a rolling wheelchair down an incline. It took a few moments to unwrap from my poncho and get control of the wheelchair. I got it stopped, and DD ran to me and said OOPS, SORRY MOM!
