Since we're on the topic of comparisons, I guess I'll chime in.
As you can tell by my sig, I've been going to HHN Hollywood for quite a long tine. I frequently go there because I live pretty close to the park. Orlando, I've been able to more frequently recently, but I go there when I'm able to.
While I do think HHN Hollywood has absolutely improved in recent years (Except 2021. Let's forget that ever happened. Lol), I still absolutely prefer Orlando. Like others have said, it is on another level. Although I have noticed some set design or scares get repurposed a bit more, HHN Orlando is still an event I would go out of my way to check out because it's consistently great. Even 31, which I felt was one of the weaker years I've gone, was on another level compared to Hollywood. With some rare exceptions, (Like AVP) Orlando's scenic always blows away Hollywood's event. I do like how a lot of the houses tend to be a more grand-scale spectacle.
Now for Hollywood's event, if I lived in neither state and I had to chose between Orlando or Hollywood, I would go with the former no question. If I lived out of state and wanted to check out California's haunts, I would absolutely check out Hollywood, but make sure you check out Scary Farm! I personally enjoyed it more than HHN Hollywood this past year. While Hollywood's event is smaller in scale and doesn't quite have the space and budget that Orlando has, they use the limited venues to their advantage. Monstrous is a perfect example of that. The cramped spaces allow for a lot more raw intensity in their houses. Not to mention they have the actual film history on their side.
While I do prefer Orlando's event overall over Hollywoods, I'm going to share a bit of a hot-take: I think Hollywood does IP houses better than Orlando....generally speaking at least (I'm lookin' at Weeknd, Chucky, TLOU, and Blumhouse). Since Murdy runs Hollywood, he is all about those IPs so the Hollywood team seems to have a better knack for that. They also have access to a good team of mechanical engineers so there's that.
But yeah, I love both events. Orlando I tend to favor more, but Hollywood has its charm as well! They use the limited resources to their advantage!
