Basically I need a festival this summer, in the UK preferably but I could cope with a cheap one in Europe. Hopefully costing under £160 including travel and a ticket. (I live in London)

I want a reasonably large one with some good bands on the lineup and that isn't sold out yet. I'm pretty desperate here as I have no holiday this summer and want somewhere to go for the weekend that I will thoroughly enjoy.

Any suggestions are welcome.
