This picture shows part of the wheelchair queue for Small World at WDW. The line to the far left of the picture is where guests with wheelchairs wait when it is almost time for them to board. That area is ramped failry steeply and has a gate at the front, so guests can remain in that area until they board. When they board, they will usually be going into the boat right in front of them, so no crossing across traffic.
There is a parking spot for wheelchairs and ECVs behind it (toward the front of the picture) and some guests may be asked to wait in the area in front of the wheelchair/ ECV parking area, especially if they will need to be in their wheelchair or ECV until boarding.
The next line, which has a CM standing in it, is the beginning of the exit line. Guests with ECVs who need to drive their ECV to the loading area will be brought down that ramp by the CM for boarding and then the ECV may be brought back up to the parking area or parked just across from the boat.
The third row is the second part of the exit ramp - again very steep and it is used by all guests to exit.
The chained off area /next row is the handicapped waiting area. It is quite steep and many people pushing wheelchairs angled them sideways while waiting in line to avoid the wheelchair rolling. It is wheelchair and ECV accessible.
The 3 times we rode Small World in this trip, that line was backed up all the way to the top most of the time. A lot of the people in the line were not using wheelchairs or ECVs and would probably have had a much shorter wait in the regular line. In our case, I watched the progress of the group that entered the regular line just before we entered the handicapped line. They got on and finished riding before we were loaded.
Above the handicapped line, you can see the start of the regular line.
