That's kinda how I look at it with everything else that contributes to the cost of what you wouldnt see vs who you would for longer sets without the costs invovled. I bet the differenceonce you've entered in a day of beers and food suddenly changes. For who I'd actually really be bothered about, it would always be about the bands there as much as the campsite and banter is fun....so is £11/12 a night with mates away on a camping trip. But if I have some bands I'd genuinely like there then I would much prefer there to be more so I can make the best of it.
