I know people that don't even bother with Universal anymore because it's just shows. I can understand that from many perspectives because it's true, it seems a bit cheap.
In all honesty, I only frequent the area because I like to ride the Studio Tour to see what's new. You can't convince many with that same angle. Those shows stay relatively the same with each visit, years apart.
HHN on the other hand is perfect. Rides, mazes, shows, scare zones and Terror Tram. "How is it they have more content for a month than they do the rest of the year" I'm sure is running through many minds. And mine too.
I want it to be an all day thing, I want to have a much bigger adventure but having so little to do in so little time (closing at 6 is a bummer) and I want some of it to be at night too. But nothing fills up the day and doing repeats gets old quick.
I'm taking a break from Uni other than HHN until Transformers, but that's just me personally.
