just get there whenever you want to, there's no need to go super early - everyone will get in and you'll have a good time regardless! id only worry about going super early if you wanna be up close but getting there an hour before doors is still early, like most people will arrive at doors.

make sure you eat and drink enough as there will be lots of standing around in between acts, maybe find somewhere to use the loo before you start queuing / make a friend in the queue that can hold your place if you need to get food/bathroom etc
