Justice as sub, during daylight would be ass. Their light show adds massively to the experience. I much rather sufficate in the tent and get the full experience.
I think the price is too high for the more casual audience, considerably above APE for example, and they're banking on the HMV dads who clearly still have their hands in their pockets. MK is the not the easiest, but a straight run up/down the M1 for many. Probably going to be freebies, and I may regret buying up front!
