First time camper here

I know the joke is, “when they say they’re lining up at 4, they really mean 2” etc. well I’m gonna be honest. I’m lining up at midnight and it’s gonna be midnight. I’m bringing layers and blanket for warmth, zero gravity chair to lounge, snacks, the whole 9 yards. I’m prepared. But the one thing I want to know is; once I receive my voucher, what area inside the store do I go purchase a card? Are people who got vouchers behind me going to try and sprint past me to the counter where you pick a card? Thanks in advance!
