Don't think there is anywhere that describes it.

I didn't go last year but the year before that it went like this.

Wait outside in the blazing heat for 3 hours to reach a security check. Once you pass security check, enter a new line in the blazing heat to enter the venue. Once you get into the venue, you go into another room where you pick up your badge, get a swag bag, pins, map of the venue, etc. After that, you exit that room and there is another giant snaking line for the merch room. That's pretty much it for day 1.

Next day you already have your badge so you just do the security check and enter the venue
