A note about parking...generally once you go through the main gate, you follow around for awhile with the rest of the cars and then there's a blue line painted on the ground and you follow that to the parking at the front. EXCEPT when they move the parking area (this happened to us at Epcot). So basically stay alert and check with the parking attendant, who can point you in the right direction.

Yes, don't just blindly follow the blue line because you could end up at a dead end in an area they are not using that day or one that is already filled.
Also, be aware that there is no tram service from the handicapped parking areas and the distance walked to the entrance can be quite far. There are courtesy wheelchair to shuttle from the handicapped parking area to where wheelchairs and
ECVs can be rented, but the corral for those wheelchairs is usually at the front of the parking area ( which may be some distance from where you are parked). Also, there is no guarantee that there will be any courtesy wheelchairs when you arrive.
For those reasons, WDW recommends that guests who did not bring theirown wheelchair or
ECV should strongly consider parking in the regular lot and using the parking trams if they are able to step up into the tram. That is the way to get the closest to the entry.
Also, it is possible that the handicapped lot will be full when you arrive. That happeened to us in AK and the Studio in March 2011. When that happens, the person with a disability can be dropped off near the entrance and the driver can then park and catch up later. At Epcot, we had difficulty finding a spot, but were able to park way out in a CM parking lot. So, be prepared that you may not be close.
