You and I had the same exact experience yesterday. Those first two/three hours were incredible; was able to do SLOP, JW, Mummy, Transformers, FJ, and the coaster no problem. Hell, even had breakfast at Three Broomsticks right after SLOP before going to the lower lot and we had the entire restaurant to ourselves right up until the last few minutes we were wrapping up.
After noon, though... Ugh. We got in line for The Simpsons around 12:30 and didn’t get off it until 2:15. And then right after that we went to the Studio Tour, which was listing a 160 minute wait time and stupidly figured maybe it wouldn’t be so bad... Wrong! In line by 2:25 and didn’t even board the damn tram until almost 5:00, and it was a BRUTAL wait.
Doesn’t help that I saw many single riders getting entire tram rows to themselves, which just destroys pacing. I saw kids actually CRYING, begging their parents to leave the line to go do something else. Hell, the only reason we didn’t just leave was because we’d already sunk too much time into waiting. Really, really sucked. Like
@Clive said, they really need to sort this out, because in a 9-hour day, having to wait FIVE hours out of it all for only two rides immediately soured the positive experience of the first half of the day.
And yeah, people not understanding the line markers was incredibly annoying. We had to repeatedly ask people to step back away from us; most did, embarrassed, but others gave attitude. And as the day went on, I saw more and more people in lines with their masks off. I even saw a woman busy on her cell phone while her two maskless kids were going crazy, and one of them even firmly placed their lips on a metal railing. Nasty.
