How many make park reservations vs find as you go.

Please remember that not ALL Walmarts can allow overnight camping due to restrictions by local ordinances.

We usually reserve when headed to travel "destinations" and especially during the summer school vacation season. Since I am the driver, I prefer to know that I have a safe place to park when on a timeline/summertime. Otherwise, off season, we like to free-form our travel plans. Happy trails!
