I end up going there every year. My sister lives in Royal Oak a block off Woodward so I have a place to park & somewhere to crash when I need to. If your bringing a classic car I would suggest if you plan to do any cruisin' on Woodward to do it on Thursday or Friday nights. Theres just too much traffic on Saturday. One big traffic jam. Better to just park and walk to see the cruise. A good street to park on is Washington in Royal Oak. I dont know how much time you have to spend in the area but Flint has a show the same week called Back to the Bricks. The big day there is Saturday, but I think Friday is a better time. All the cars are parked downtown and there's really no cruisin'. Better show I think.
If you need more info on the area let me know.
