No Skip - here's my idea of some differences between Cambridge and festivals like Sidmouth and Whitby:
1 - people go to both for the music, but they like different kinds of music
2 - People go to Sidders and Whitby much more to participate, not just to listen. Especially Sidmouth with its numerous workshops.
3 - What Leadfingers said about networking. Though THE networking festival is the National at Sutton Bonington, which is full of organisers who go there to chat, gossip and throw around ideas and plans with each other.

Anyway, I'd hate all festivals to be the same!
