The 'vibe' is much nicer than Reading. It's a younger crowd but also a mix of people- not like Reading where it's almost exclusively teenagers. The crowd which gets drawn is more dependant on the line up too.
However, in terms of 'areas' - it's pretty boring. If you're not going mainly for the music, it could be a bit underwhelming. There's really only the main stage, the main tent and a few smaller stages. There's not really anything else happening in terms of scenic locations or entertainment.
