Stepping in for a second but, let me bring this..point; if you will. The benefit Knotts has had with their mazes is that while yes--a majority of the mazes are repeated...it isn't like they can be the exact same maze over and over again. Each year, some change comes in and affects itself for the event; in one way or another. Knotts has been a prime candidate for "Improving your dated product"; while when the Hollywood creative team does the repeated mazes, they are for the most part; a copy and paste of that product, minus any cuts made to allow the flow of the budget to go into a larger quality maze.
Both events have flaws in their own way; but if it's one thing that I actually give Knotts the edge, is that they refine the experience and update according to the feedback and consideration of GSAT's. And they have been innovating in technology and effect works that go beyond a lot of the other events in the SoCal market). Now, that's not to say USH hasn't had great mazes at the events, especially in the past few years. But you can tell through Hollywood's events, a level of predictability that is present with most of it's mazes. Atleast with SFMM, the mazes represented do have things that can be more surprising.
