The whole point of VIP is so people with too much money can feel special by paying over the odds for something. It's not aimed at you.
I said it on the FC forum, I got a freebie VIP at Hellfest a couple of years ago, and it's really nothing for anybody to feel their missing out on. Food and drink with a bit shorter queues, an area to chillax for a bit with less people and a bit of shade (probably less of an issue in the UK

), I wouldn't pay any extra for it to be honest, but it's not aimed at me, it's aimed at people who fly business class on planes. If it was available for cheap then too many people would do it which would defeat the purpose.
