We stayed here on the very last night they were open this season. The staff was very friendly and they actually had campsites that were more private then almost all the Michigan state parks we have stayed at. It was a bit pricey for camping $40 for a pop up truck camper with only electric and water. 

They have hot showers that were clean and looked taken care of. They have a  playground, playroom and a pool. None of this was open during our visit but I imagine in the summer it is all going strong and the kids have a blast. My one complaint was it is pretty close to the road and during a heavy tourist season it could probably be pretty loud.
