I'd say it's borderline now, Rob. In previous years I hadn't really noticed the VIP area but this year is a lot bigger or has moved. I took my usual spot, which is bang in the middle and about 20m-30m from the front crowd barrier. The VIP area was clearly in sight to my left. It didn't cause any inconvenience for me, but still think on a busy night thats a lot of space taken away for regular punters.
I think it's fair to say they make a killing with this VIP thing though. Bit of simple maths:
2013 apparently 150 seats available. If this year is bigger then assume 200. Adults £99, children £79 - so the average is £89 x 200 = £17,800. Over 3 nights thats £53,400
It'll probably cost them a couple of grand to hire the raised deck, and then other costs are probably quite low. 200 seats and 100 tables. A hog roast per person, and a few crates of cheap champagne. Few staff members. Probably looking at 7k-8k in expenses.
Around £45,000 in profit from 600 customers isn't too shabby, that's on top of the other 25,000+ people each night paying regular prices.
