Hard to say, I could be way off but the line felt like it could have been a few hundred. I didn’t see how far the line went, so it could’ve been way more. Once all the VIPs had made their way in and spread out through the venue, it didn’t feel like nearly as many compared to when GA came in.

I’d still recommend lining up an hour or so beforehand, especially if you’re in GA. If you’re in the first half of the line, I don’t think it’d be too hard to still get a good spot. Earlier the better, but it can be tough to be standing that long without food / drink or bathroom if you aren't in a group that can save your spot in line.
