Yes, but be aware that if you are parking in the handicapped parking lots at the WDW parks, there is no parking tram to take you from the lot to the park entrance. In most cases, you would be getting closer to the park entrance by parking in the regular lot and taking the tram.
At AK and the Studio, the handicapped parking areas are close to the entrance. At Epcot and MK, you will have quite a hike.
