On the property, last time no they didn't. But then again, I also recall they said nobody could line up before a certain time the morning of the show, and apparently there were people lining up a couple hours before that. Rose bowl security was a mess, inconsistent, and unreliable. We'll see what happens this time.
That's probably why the mess occured. If they say no camping and starting a line early, then you probably shouldn't bother creating a line the venue won't folllow lol. All you're going to create is internal conflict among angry fans
