A couple locations for consideration-
Lake Geneva, Wisconsin, it has-
the lake (duh), stores, restaurants, decent roads, motels if you need.

Starved Rock State Park, near Utica, IL it has-
Likely more driving, BBQ type situation, hiking, fishing. There is lodging/stores/restaurants near there too, but it less metro than LG is overall. Disclaimer, I haven't been there in years, I am going off reading only.
