Camping for Thursday and Friday nights

I realize that I am extremely late to the game on this, but I haven’t had much luck securing a camping spot from afar. My husband and I are attending the festival for 1 day (Friday), so we’re looking for a place to camp on Thursday and Friday night.

I guess my concern is more about getting to the festival, so I am wondering first if the parking lot that the shuttle stops at is large enough, or if it often fills up quickly. Other than that, I’m wondering about a relatively nearby campsite that we can ride bikes in to town from.

I’d love any advice or insider info that anyone may have to offer!

Thank you
