I think saving Hotel, Blumhouse, and Universal Monsters for the end definitely makes the most sense. Those lines never build anywhere near as bad as the others. Then hit Weeknd dead last right before closing. The only thing I'm nervous about is how long Terror Tram will be -- it's nowhere near worth more than 45 mins at most but it's often double that. Knocking out Klowns, Halloween, and Scarecrow before 8pm seems so crucial. Get in line for La Llorona while it's hopefully maybe an hour at most. I gotta do dinner at some point, so I have that at 9 -- will try to make that a 45 min break at most, but sometimes it becomes an hour. Weigh whether or not Terror Tram is worth it -- if anything, hitting it right at closing for that would make a lot of sense too (11:45), that way they're not letting in any Express and they're just zooming you through. Enjoy the small waits for Blumhouse and Hotel. Head down to Universal Monsters. If you're super lucky with a lot of time left, hit Jurassic or Mummy. Weeknd is the finale of your night.
Can't wait to try out the method, regardless.
