We had a wheelchair last time because my mom had just had a knee replacement three months prior to our trip. We referred to the chair as "The Magic FastPass" because it often did put us in a different (ie, faster) line, it seemed...although again, these were more for the regular rides and not the coasters, etc.
It may seem that way for people who are unfamiliar with using a wheelchair, but in actual fact, it doesn't actually work that way.
Many times, it seems to you that you are getting on faster because you have moved, but if you could see what was happening in the 'regular' line, you would know that you didn't really move much (or any) faster.
Some examples from our last 2 trips (March 2009 and October 2008):
- At Small World, some of our party went on the handicapped accessible path (the line has a pull off point after the second turn). The rest of us stayed in the regular line. The part of the group that went down to the wheelchair boarding area got in just over 2 minutes before the rest of us. But, we have also had the situation of waiting in the wheelchair boarding area for 25 minutes when there were lots of people waiting there; that was when the regular line was a 5-10 minute wait.
- At Toy Story Mania, we had more people than can fit on the wheelchair accessible ride car (2 can fit in the first car and 4 in the back - maybe a few more if they are small children). The pull-off point for TSM occurs just after you get your 3D glasses; if you follow the main line, you come to stairs. The accessible line has a ramp. You can see the accessible boarding area from the regular line and go right past it as your ride is over. Those of us in the regular line finished our ride before the members of our party in the accessible area had boarded. From the time we got off, it was almost 20 minutes before they joined us after riding.
- At the Nemo ride at the Living Seas, we had to wait at the front of the boarding area for a wheelchair accessible ride car. I didn't start counting right away, but after quite a few people passed, I started counting and more than 50 passed us to board while we waited.
- At Buzz Lightyear, the pull off point is at the regular boarding point so when we are getting pulled off, the 'regular' line is boarding. While waiting to board at the exit, we frequently see the people getting off who were waiting just ahead of us in line before the line split.
AK and the Studio were built with all Mainstream Lines, which means they are wheelchair accessible and people with wheelchairs/
ECVs wait in the same line with everyone else. The wait should be the same, but can sometimes be longer (like we have waited 40 minutes longer at times for the accessible Safari car). There is also the possibility that someone with a wheelchair or
ECV may arrive and find there are no wheelchair seats left for a show, even though there are seats available for people without wheelchairs/ECVs. For many of the shows, CMs pull people with wheechairs and ECVs out of the general line and have them wait in a different spot so the number of wheelchair/ECVs for that show can be counted. It may seem that someone is getting on faster, but they will be in the same showing as they would have been without having a wheelchair.
Epcot and MK have had attractions changed to Mainstream Lines if possible during new construction or renovation.
People who have kept track have pretty consistently posted that they got in sooner about 20-25% of the time (but usually not significantly sooner - like our one Small World experience), about the same about 50-60% of the time and longer about 20-25% of the time (sometimes a lot longer like our Safari wait).
