I really don't think it's necessary to line up all day like that. Doors open 7.30pm. that's plenty of time to go in, grab a drink and find a spot. there'll be natural movement around, I know i'll be wanting to check out the stage from different angles and just enjoy the experience. I really hope that I don't encounter people like I did on 360 that didn't understand general admission means there are no reserved places on the floor. so if someone comes along and stands beside you they are entitled to do that, they have paid their money same as anyone.
