You will like the Park, I would suggest the end sites in any of the C loops. We stayed at C 14 and it was big and rather private. C 15 was great too. The beach is nice, a short bike ride away. Cedar Point is terrific. Put in Bay is not for the kids, especially on the weekends, it's quite the party place for adults. Kelly's island is much more kids friendly. We used to take our bikes on the ferry and make a day of it exploring the island. Look for Toth's Ice Cream in a nearby shopping center. Marblehead Lighthouse is a must see, charter a fishing trip for perch or walleye fishing.
