Rocky Arbor is beautiful but it is RIGHT ON the interstate, and can be pretty noisy. Maybe not so bad if you're lucky enough to get a campsite at the end away from the road.
Wis. Dells has all the hookups you'd need, perhaps not a woodsy atmosphere but if you have kids along, it will have some activities & clean facilities. Ask for a site in the upper area of the campground; the lower area is by a train track (which is used). (Disclaimer: KOA owners are friends of mine - but we have stayed there several times. They're a nice couple and work hard to keep the CG nice.)
Our favorite in the area is Mirror Lake. Not all sites have hookups. The state parks are VERY hard to get into; Wisconsin takes reservations 11 months in advance, and especially at the Dells, or on weekends anywhere, those sites book up fast.
