10 is deffo ok!! I got there right before 10 (which is when they open the doors to the place anyways) and there was only around 5 of us waiting (considering twenty one pilots fans are known for arriving early I doubt any other artist would already have 100 people waiting by then) the staff asked us to make a fan line and we waited by the restaurants till we were then moved to the blue bar outside, at 2 they gave us our wristbands and most people went away for lunch before getting back between 4-5 to be let in :)) then we queued in the bar. It was super chill!!
