I've never been one of those "omg working the festival is so much better I'll neve be a punter again" people, BUT the free daily shower is a huge draw I must admit. I was very dismissive of it until I had the option and it's life changing. Any hint of hangover is 50% relieved by a shower (although tbh I prefer to beat the queues and shower when I get in at 4-6am then go to bed clean... Wonderful).
Sorry, that's not made you feel better has it?
