We're getting to the point where the event is no longer "fun" because of the crowds. We know the ins and outs because we're fans and we analyze this event to death - the average joe tourist does not. When they show up and only get two houses done after waiting for five hours and they can't even find actors in scare zones, they aren't going to be happy. Then you've got bad blood, bad word of mouth, and someone who isn't returning.
Universal DOES need to find a way to thin out the crowds. The park can't sustain these numbers: this was opening weekend. Imagine what's going to happen come Hell Week. Sell-outs are super possible, but believe it or not, I would guess Universal isn't the most interested in sell-outs. Sell-outs mean the foundations of the park get pushed to their absolute limits - and more guests aren't having a good time, meaning they won't get their money again.
You guys can jump through as many hoops as you want about why your money spent justifies the ticket price, but the reality is Hollywood made these moves and Orlando will, too. I frankly don't blame them, as someone who has used the Rush of Fear pass every year since its reintroduction. (Again, I think a weekend pass will replace it.) Universal is currently dramatically underselling their park, and I simply don't believe it'll continue, especially when the other shoe drops on crowds this year. If they max the Studios, and don't want to spend the significantly higher capital to expand to Islands (they don't), they'll find a way to make more money off of less people at the Studios.
