So I'm making a teepee that will fit like ten people inside, I plan on arriving pretty early and I want to be able to set this thing up. Will I have enough room? Is there something I can do in general camping that will give me enough room to set this up? Will the people directing the cars even let me set something like this up? (It'll be like 12 feet tall and maybe 20-ish feet in diameter) There's going to be about ten people sleeping in it, we're driving 4 or 5 cars down.
