How much should a night of camping cost?

Hi everybody! This is my first time posting to the forum. The cost of nightly stays is interesting to me. I'm trying to figure out a way to make an all-access pass for year-round camping and could use some feedback. If this interests you, please give me feedback by answering a few quick questions!
