The KOA is Monroe County KOA, it's over near Detroit area. However, we live near lake MI so that's where most of our camping is. Best, favorite place by far is Poncho's Pond in Ludington. Ludington is a great town, there is a city park along the water with huge playground equipment where you can watch the cross-lake ferry come in and out. That's one of our favorite spots to visit when we are there.
Poncho's is very clean, staff is extremely friendly, and the facilities are very nice. 3 swimming pools (one indoors), playground, fishing pond, nice paved roads and patio sites. We were just there for memorial day, I can't recommend it highly enough.
we haven't really done much camping further north than that. Once in Mackinaw City, but that was many years ago.
By next year, the one in Grand Haven might be good to visit again. We camped there when it was a Yogi Bear Jellystone park, but then it was bought a couple years ago by a horrible management company who made wholesale changes, made it into a NASCAR park, ticked everybody off, then lost the property to the bank. Now it is bank owned, but the manager is trying to return it to what it was back int he Yogi Bear days (minus the actual Yogi Bears). I couldn't even tell you what it will be called, but the facility itself was always pretty nice, great playground, kiddie pool and big pool, lots of activities, hay rides, etc.
