The Sutton Lane camping site will be in operation (with shuttle bus service into the town) but MFAB's site doesn't mention the Sports Hall camping site anywhere. You could try putting the question on the site forum to see if anyone from the festival can give an answer. Be warned, though, no one seems to look at it very often.

Really, we could do with someone from the festival committee taking a look at this thread, with a view to getting the answers. I'll see what I can do.
