Open Question: First time camping...?

My first real time camping. I have rented a pop up trailer to pull behind my truck. Going to the Interlochen State Campground near Traverse City Michigan during the Fourth of July weekend. It's pretty huge over 700 camp sites and the whole place is booked.

So to save myself some embarrassment and maybe doing something foolish, any advice on setup, parking, leaving, or anything else you can think of? Thanks!
