HI Listees!

Still working on my vacation plans for this summer. In August we have a
reunion in South Haven, and I want to camp there in my vanagon (required
content)>Can't afford the pricey vacation homes. Woodalls mentions two
parks, one private, one state, in the vicinity. There is also a KOA in the
area.
Here are my questions:
Has anybody ever camped there? Any recommendations? Any suggestions?
How about sights/activities in the area (two kids 4 and 6)?
TIA

Cheers,
