It sounds like another Frozen debacle, putting a popular IP in a ride that can't handle it. I also think in general IOA needs to replace lost Continent faster because that was also a people eater. They got rid of 3 things that ate people. Well Fury a little less, but the other two one being a show was a lot of capacity and 2 of the 3 was no height restriction capacity which is vital in a park. I don't know when parks will realize that lower height capacity is really a separate category. Certain new rides will be more popular because they have a low to no height restriction which means more people entering the park can and will ride it. Velocicoaster will always be more popular than Hulk and HRRR even when they are all old because of that 51" height. Outside of IG (48") it has the best height restriction for intensity in the Central Florida area.
Honestly they are not adding enough to IOA quickly enough and it annoys me that the replacement for lost continent is so far off. If Disney shut down an entire area 4 to 5 years before its replacement we would be all over them, but people are all, it is OK, we will eventually get Zelda. Kong opened in 2016, since then (8 years in July) they have added 2 things (Hagrid's and VC) and lost 3 things. But the issue is that 2 of the 3 were no height restriction and 2 of the 3 were people eaters. It has put too much stress on the other rides causing the long lines. Now the two they added (unlike Studios additions) are AMAZING (one I am going by reviews since I haven't been on it) and I give them props there, but that only adds to the lines of those two things. VC and Hagrid's were VERY rarely under 100 minutes over the holidays. Sometimes peaking at 180. For rides that are several years old, the lines should be coming down a little. When they don't (like Mine train and Frozen over at Disney) it normally means a capacity issue or not doing new things often enough in that park.
I love Universal and I can't wait to go to Epic, but I sometimes wonder if they tried to grow too fast. They really needed to stabilize their parks and I feel history is repeating itself as their competitor down the street did the same thing. Because when you look at numbers Disney has actually added way more capacity over the past 8 years than Universal and way more net positive new rides/shows. The number of 100+ minute rides at Universal was pretty insane to me.
