In reply to timjones:
Yes it affects Camp 4. However they offer free bookable camping for those directly involved. Commitment is as much as you can provide. We focussed on steep slopes below parking areas to clear a lot of trash quickly that others might struggle to get to. And climbed the other half of the day.
As for the evening events imagine if Kendal was only populated by keen climbers and its all free (except beer where they do good deals).
The whole thing is great fun and linked into archeology, the ranger service and local climbing activism.
