Be ready when an opening appears
An alert does not hold a campsite. Have your reservation account and trip details ready so you can check the site's rules and finish booking on the official website.
Watching several suitable campgrounds or a wider date range gives you more possible matches. Keep a backup plan: an opening may be booked before you reach it.
