I'm of the opinion that a year-round maze doesn't fit in a theme park like Universal. I hope there's something to it, because another House of Horrors rehash would be a disappointing addition.
I can't name another major theme park on Universal or Disney's scale that has a year-round maze. If they want to pursue that direction, that's their prerogative. But it seems inconsistent with what they're trying to do with the park thus far.
