They should be able to answer your questions. It's been a while since we stayed at POFQ, but I remember there being more than one parking area.
it doesn't show the parking, but I think it's located infront of and on each side of the resort.
A few years ago when we stayed at French Quarter we had a room in Building One facing the parking lot. The parking lot closest to us had several handicapped parking spots which I used.
