Peninsula State Park is a huge state park with five campgrounds with over 400 sites (not including group sites) and it can be overwhelming trying to decide where to stay. Our decision was narrowed down somewhat because two of the campgrounds were closed for the season. We camped in South Nicolet along Nicolet Bay for two nights. Our first night was on the water but because heavy rains were forecasted, we relocated to another site closer to the bathrooms for the second night, putting up with the “hum” for a closer dash in the rain. There is so much to do in the park itself and Door County in general. However, we were here during the week in October so while the campground was quiet, bicycle and boat rentals were not available. Many great hiking trails. My only beef is that Wisconsin State parks charge more than many other states and, in general, facilities are not always as well maintained (bathrooms were a little dated and not the cleanest but sufficient for a campground). Still - this is a great place from which to explore Door County!
