LaVern Camping on Tuesday

Hey this is my first time attending Rocky grass. I am thinking about going to Lavern Campground this evening with my son for an extra day of camping. We have the Lavern camping and car pass and I am curious if I am going to have to break down my camp at 6 am and get in line to get camping again or am I able to stay wherever we are?

If you reserved and paid for a site through campground you can stay in the spot.
