Here's a link to
another active thread from this board about an ankle injury.
Even though it may have seemed like that to you, most attractions don't have a handicapped entrance and you do enter thru the regular line. Lines that are wheelchair accessible are called "Mainstream Lines" and people with wheelchairs/
ECVs wait in those lines with everyone else.
AK and the Studio were built with all Mainstream Lines. Those kinds of lines didn't exist when MK and Epcot were built, but they added Mainstream lines as much as possible when attractions were added or renovated. There were some that were not able to be made accessible, so they still need a handicapped entrance. That doesn't necessarily mean a shorter wait; on our last 3 visits to Small World, we waited for 25 minutes when people in the 'regular line' were getting on as fast as they could walk and some boats were not even filled.
