How early should I arrive at a concert?

Question

I'm going to a twenty one pilots concert in a few weeks, I'm in the seated area but I've never been to a concert before and I don't know how early to arrive. I want to get there early enough to buy merch before the show starts (I don't want to miss any openers). It starts at 7pm.

Answer 1

Early enough to tell Mom where you're sitting, what time the concert will be over & where to pick you up. 5 hour head start.

Answer 2

you could try showing up at 6:30

Answer 3

You should check whether that means the show starts at 7pm or whether doors open at 7pm and the show starts later. There is a big difference.

Answer 4

I'd get there 6.15pm
