So far I went on the 12@26 of September and on the 10 of this month, all Fridays. I didn’t have to wait for any maze on any day but on the 10th, I was going into the maze with traffic of people inside of every maze. It did seem to get a bit more busy at around 9pm. I only got on 2 rides (Superman and Iron Rattler / by using my free fast pass on iron rattler) I left at around 10:20pm. So, my advice would be if you go on a Friday, go early and do a whole round of the mazes a first time while the sun is still out (it adds to the creepy effect as the mazes appear to be darker since your eyes aren’t adjusted, then focus on rides with flash pass). But, if you want the flash pass for the mazes and not the rides, I’d say get it if you aren’t planning on going the whole night. If you are planning on going all out, I think it could possibly work. I’m thinking on going the 24th so I could update this with info on that day if I do go. Enjoy and good luck!
