Welcome
azebb & partner!
You will be given a map and other things by Greeters (one step past gate) so that you'll know where open camping is.
If you really want to be with a camp, you can reach out to a prospective camp with a cover letter-style email explaining why you like them and what you offer . . . (if you see something excellent) . . . but technically it's a little late in the year to do so. Most camps close by April/May/June.
Also, since you already have a lot of infrastructure, please don't imagine that it's "a must" to be with a placed theme camp in any way. That's only something you should do if you find a group you mesh with, & desire the work shifts, cost, and responsibility. You can still call yourselves whatever you want, hang a sign out, invite your neighbors over for cocktails and canapés. And you can still visit theme camps whenever they're open.
