There are several basketball courts sprinkled around the campground. While not on the map, I think the closest to any cabins it the one between the 1800 & 1900 loops.
As I recall (correctly, I hope!) there is a basketball court on the same side of the road as the cabin pool. There aren't any playgrounds on the cabin road, though.
We were in the 2500 loop, and there was a basketball court just past the pool/laundry building, heading back towards the main checkin area. We saw b-ball courts all over while taking the buses.
