My 8 year old son uses a scooter (medically prescribed and personally owned) for long distances and to conserve energy. He has Duchenne Muscular Dystrophy. He used it at Disney for the first time at the end of May. We had no issue at MK or EP, but did run into some negative encounters(they way/tone that they used and 1 very inappropriate question) with CM's at AK and DHS who, in summary, told me my child could NOT drive his ECV as Disney did not allow it. It was not due to his driving ability(he did not hit anyone and he is overly cautious and slow) It was so bad at DHS that we left the park after a couple of hours. I did stop by guest services and got the email of who to send a note to, which I did that evening. A supervisor did call me once we were home and we spoke about the situation and possible remedies for about an hour. I had hoped things would be better when we returned yesterday to go to the Frozen Summer event, but in fact they were worse. I never even got out of guest services before the trouble began. I spent over an hour there and had a long discussion with the Park Duty Supervisor who apologized and tried to remedy the situation(and really was very nice). They kept referring to their park policy that no one under the age of 18 may operate their rented ECV's. I won't go through our entire conversation here as I reiterated that it is his personal mobility device and a long slew of examples. The fix for yesterday was to put a blue tag on my son's scooter. He also said that they were giving a "one time exception" to the rule so we could enjoy our day. My response was "What happens next time? His scooter is not a one time exception, but a daily use item." The Park Duty Supervisor said that he can't make any decisions above that and that he understood completely and that someone higher up would be calling me in a few days. I don't want to start a debate or tirades of anti-Disney comments with this info. I still have faith that Disney will get this right. I have presented this info to make sure that I understand the ADA requirements correctly when I speak with Disney this week. It would seem to me that they would be out of compliance to refuse my son(or any child) to be able to use his personally owned, medically prescribed mobility device provided that it is not a device that doesn't meet the requirements for a mobility device(I know the Segway brought issue up) His ECV is a 3 wheeled Lynx L-3. I know that Disney would never tell a parent of a young child in a power chair that they could not use their chair in the parks. The scooter is my son's power chair right now. Is my understanding correct?
