Are there reserved seating areas for people with disabilities to view the parades? Specifically, wheelchair accessable areas? If so, are these "good" viewing areas or are there alot of people in front of you? And do they fill up quickly? We didn't watch any parades last trip (well, we did see the one at MGM) so I have no experience in this area because my son was still using his stroller as a wheelchair. As always, thanks so much for any advice you can offer!!!!
