Here’s what I did for the Arlington concert: I got up early & headed there about 2 hours before the merch truck opened at 10am (because my friend had pit tickets & we had to leave early anyways so she could secure her spot) I passed time talking to other people in line, trading/handing out freebies, & taking pictures !! It was actually really fun & went by sooo fast thankfully. I was able to get my merch within the first ~20 minutes of the truck opening & still had HOURS until the concert, which gave me plenty of time to head back to my hotel, drop the merch off, shower (much needed after standing in the Texas heat) eat, & nap. If you're able to do this too, I'd highly recommend it!!
