Ohio has a number of really good state parks and you can find them via an Ohio State Parks Web Site. This link should get you to it...
https://parks.ohiodnr.gov/camping. One we liked quite a bit is the Indian Lake Park, they just put in a heated pool for campers around a year ago. They do have have full hook-ups in areas facing the lake, but you need to reserve ahead to get them. You can do that via the web page as well. They have a few discounts you may be able to take advantage of if you look. As Ohio Residents we can camp for half price Sunday through Thursday. They also have some military discounts. We haven't gotten to the Amish County, but have heard a lot of good things about it. Hope this helps, have fun.
Having some trouble figuring out how to reply, hope this works.
