Yoko Kanno Question

So I was planning on buying a three day pass but I have work Friday so for the Friday event I was planning on showing up after 5 before the concert starts. I was planning on buying the tickets ahead of time. Is 5pm too late for a badge registration? Do they stop badge registration at a certain time? I want to know before I buy the tickets so I don’t get a rude awakening when I walk in lol
