I went to the Wizarding World for the first time today and was surprised with the crowds...
I got there at 9:30 and the Wizarding World was already packed. We walked in through the Lost Continent area and found out HP was closed off. They walked us over to Jurassic Park, where my girlfriend and me got two orange tickets to get in HP. We walked BACK to Lost Continent, where we were instantly allowed into HP. I thought this was a waste of going back and forth, but we got in and I was happy with that.
Forbidden Journey had a 60 minute queue in the morning. It zig zagged outside in a curious fashion, so a whole lot of guests accidentally(or purposefully) skipped several people every few seconds, and there was no crowd control in the area. Even after we got in the castle - there's the queue to the right of a narrow hallway and an empty queue-looking area to the left - a lady and two children went from the queue to the unused queue-like area and began darting down the line. No one stopped her and no one said anything. I was pretty upset, but the ride was incredible. Unfortunately, crowds didn't ease up - the queue got progressively longer throughout the day, culminating in a 90 minute wait at 7pm.
Dragon Challenge stayed at a consistent 35-60 minutes wait time, but I realized the dragons don't duel any more. I was really disappointed with the queue, as it's very forced. There's not much story to it at all, and with the queue being as long and narrow as it is, this made the wait feel much longer.
Olivanders was packed the whole day. With 90 degree weather, I had no idea where people got the patience to wait outside for hours on end. Didn't even bother with this one.
Butter Beer was fantastic though! The Potter area was great, but the FJ showbuilding coming out in plain sight is a HUGE distraction. If you're walking from Jurassic Park, you'll see a gigantic warehouse - and Hogwarts peaking behind it. Really, really weak.
The rest of the park was packed too. The longest line I waited was for Spider-Man, which was 75 minutes. Dudley Do Right had the longest line in the park today - 120 minutes.
