As someone said earlier people with jobs and kids who do last minute trips are getting the short end of the stick. We are weekend warriors who talk about it on Monday and Tuesday, weather looking good come Thursday decide to go. I take half day vacation go to park get site wife and kids come after school. The only ones who gain from this are people who are planning a vacation around camping and retired people who can schedule that far ahead. I dont see any penelaty for canceling so most parks will be booked full on weekends for the year but empty spots from last minute cancelations. So the weekend warrior will lose out. Our local park is implentanting it. The artical has quotes saying "people travel only to find their preferred site taken or the campground is full", I don't understand who this is helping as the park gets the user fee either way. What it boils down to is the fact that state parks are cheaper than private camp grounds so there are a certain crowd that wants the best of both worlds.
