We were at #12, which shares the pool with #11 and #13. They're all next door to each other. As I mentioned, it was about a 3 minute drive to the parking lot. There's an overpass that goes over Ball Road, so you avoid that stoplight.
Those ones probably aren't realistic walking distance, but some of the others are, like #1 and #2.
