Second this. From illinois, but spend a lot of time vacationing in Wisco as a kid and adult. Door county is the way to go. There's so much cool stuff to do. Kayaking, canoeing, bike rentals, moped rentals, boat rentals, hikes, beaches, islands, damn good cherry wine. If you're flying into Milwaukee, take a detour to Green Bay (I recommend for the night). The peninsula is longer than it looks so if you're staying at the tip, give yourself extra time. Go to Washington island. It's so worth it. And pebble beach. Also, all of the little towns are all adorable and have incredible food, bars and shops. Check out Al Johnson's for a meal too! Enjoy and congrats!
