It is for all three nights it can be answered by anyone with direct knowledge. The website as well as the ticket notes when campground opens and closes and how many nights the pass is good for. It also notes any camping upgrades such as premier camping Oasis camping etc
Should be for all 3
All I can say is that I went for a 2 show weekend and the single price was good for all nights of camping which was 3.
This question can only be answered by Live Nation.
I would call the venue and ask someone directly for that info if the website is not clear.
