Based on people flow and popularity of IPs, I'm sure these will be the most to least crowded mazes...
1 - AHS (most popular IP on backlot)
2 - Shining (this and Insidious could swap, depending on word of mouth; I'm betting on this being a hit though and with Stephen King big right now, this will be like last year's Exorcist)
3 - Titans of Terror (basically in a spot on the upper lot that'll have it jammed all night with lines -- one of the first people see, big IP recognition that's advertised well, a name that's not confusing, and should test well with word of mouth; that big line will also spike once Terror Tram is closed and get even bigger -- this might be the one maze you have to wait for no matter how good your game plan is)
4 - Insidious (still a pretty big name in horror but it's been done twice; if the maze is good, and gets word of mouth, this could beat Shining)
5 - Blumhouse - I predict a steady-flow, most people will be turned off by the name and lack of recognition as to what it has to do with the IPs -- I suppose it'll depend on how it's advertised as well)
6 - The Walking Dead (still ever so popular and located near the front, will have crazy wait times randomly)
7 - Saw (not in it's prime, and the maze will have some nostalgic fans and newbies who didn't see it in 09-10, but just like the new movie, this will be generally be a flop)
8 - Ash vs. Evil Dead (the Krampus and Crimson Peak of the year -- conveniently located in the same burial ground, too -- nobody knows what the hell it is, so people will stay away from it or put it at low priority)
