I feel like the whole maze lineup needs to change to freshen it up a bit. Last year I had a run of Mine Tours that I considered trying to get a refund for because of how awful it was, Sub Species was great when it was at it's best last year but at the same time, it needs a big update for it to be exciting this year again. Story update or completely new maze, I don't mind, but just something would be nice.
As for TOTT I think it's a strange case, the maze should have been retired quite some time ago in my opinion, it's had nothing new to offer for years with the same format over and over again. I think keep the TOTT brand but just change the maze so that it's not the same pattern as we have come to expect from it as I honestly haven't really enjoyed it so much the last couple years, even on a "cheap laughs" standpoint it's just not delivered on being the entry level scare maze that is often used to justify the less intense nature of it.
I absolutely love Scarefest and the mazes it brings, but things just become bland and stale if they're unchanged for too long
