We check in tomorrow anyone know what check in time is I thought it was 1pm but can't find on site to confirm

Check in is 5pm their time (central time). Check out is 4:30pm.

My wife says 5p local time.

5p. But if the campsite is empty, you can generally set up a few hours early.

5pm cdt

If the campers have already left, they will generally allow you to check in early.
