On Tuesday I was told it was fine to go in entrance 3 even though the text I got at lunchtime said my ticket was for entrance 1. Either way, its possible to move around the back of the floor and choose which side you stand. Its worth noting for those that queued all day, that I arrived at the arena at 7.10pm, was inside with minimal queuing in 5 minutes. I initially stood about 25 feet from the barrier at the e-stage but when everyone stood up I was able to find a place about 5 feet from the barrier - perfect for all of the show in the cage and ideal for the e-stage.
