First, your ticket type determines which major campground section you are allowed into: GA camping, VIP camping, and Platinum camping. You need the corresponding car pass too, but don’t go trying to get into VIP camping with a GA ticket on your wrist… it won't work out well for you.
FYI: The sooner you arrive the closer you will be to Centeroo (generally speaking) So choose a pass with an earlier entry date for a better shot at a closer position relative to people with the same pass as you. No worries if you end up further out - because we also have a new “Jamtrak” tram system powerd by Allegiant to help you get to and from the campgrounds.
Aside from your arrival day and time, the camping spots are not “reserved” as specific plots. You will be camped with the people that arrive at the same time as you. So if you want to camp with a few friend’s cars, be sure to arrive and get in line at the same time (don't worry if you get a little separated, you can regroup right after the security check.)
