In fairness I would definitely take 3 days of camping with bands for £99 regardless of who was on. Always end up missing bands at Festivals anyway.
I honestly don't think it's that bad a lineup for the money - Tigercub are probably my favourite new band, BSP are always great and Franz are still good. I guess even if you watch and enjoy 5 bands you're getting your money's worth.
Half of the more enjoyable festival experiences are when there's a DJ on at like 3 in the morning or a cinema tent is showing Mad Max: Beyond Thunderdome and you're off you're head anyways.
