I was in room 1151, which was in one of the 50's buildings.
It was in building A, the closest 50's building to the parking lot/classic hall combined, although there may have been closer rooms to the parking lot in building B (which is much farther from the food court/check-in).
After having stayed at port orleans riverside last june, I guess i was very spoiled about having a parking spot very close to our room. in the alligator bayou part of POR, the rooms are fairly spread out and so there is lots of parking all around. there was a handicap spot about 20 feet from our door, which made things very easy.
at pop century, even the handicapped spots were much further. and, our room was not on the end of the building. just walking past 8-10 rooms seemed far. and there was then sidewalk to the parking lot and a double-sized lane where cars could drive before the parking spots began. the handicapped spots stretched out along one aisle, instead of being the first few spots of each aisle.
didn't matter, though, because they were always filled. (except when we first checked in at about 1 p.m.).
there was a well-worn short cut from one corner of the building leading right to the luggage service part of the check-in building, but it was covered in woodchips so it was difficult to use my rollator. I wish they would just pave it with brown concrete or something. Nobody would actually want to use the sidewalks and walk all around the building, but to use the
ecv you'd have to.
There was a paved "driveway" for the resort's service carts that went sort of near our room and did a turn around loop which I walked on sometimes. It didn't let out near the handicapped spots (didn't matter because I wasn't parked there) but it did naturally have a cut out so I could roll into the parking lot easily.
i'm not sure if this is the kind of info you wanted--hope it helps you.
