I have had O2 Priority for a while, and used to be able to get into the O2 Arena via the Blue Room, opposite the main entrance, with my standing ticket. Last time I visited, I was told only the first 100 visitors could get in this way, and I would need to queue at Entrance E along with everyone else. The queue was massive, and did not move until they opened the doors (around 6.30) at which point there was a massive free-for-all of people trying to get in before the support act started. As I had Priority, I tried to then visit the Blue Room from within the standing part of the arena, but was told this was just the exit, and I would need to go back out and around to the front again to get in. None of this makes sense. Why does Priority no longer give you priority access when standing, unless you arrive in the morning and are prepared to be one of the first 100 in the queue? And what about Blue Room access? Surely this is either a mistake, or Priority is no longer something worth having when visiting the O2?
