Cat and E.T. are the only current attractions with height requirements where this kind of thing would ever happen. Universal is known for having an extra kick. But those KUKA arms and over-the-head restraints pretty much require FJ to have a 48" requirement.
It's pretty much a foregone conclusion that DHS will have at least one attendance decline over the next 5-6 years.
Especially with Frozenstrom over at Epcot, AK getting some new stuff, MK still being the king, and Universal Orlando adding E-tickets left and right... where's the room for a 6th day at a park which will have 7-8 attractions for at least a brief portion of this overhaul?
DHS will be lucky to have 9 million/yr if it takes until 2018/2019 to open the Pixar stuff.
But the problem is that many of the attractions slated for closure in the near future (Indiana Jones, B&TB, Mermaid, Disney Jr., Muppets, LMA) and one in particular that's already closed (Backlot Tour) were C-ticket people-eaters in a park desperate for them. Or they're A/B (One Man's Drean, Captain Jack, Animation, etc) meant to divert guests off pathways.
DHS can't feasibly sustain 10m+/yr with just TSMM, GMR, Star Tours, ToT and RnRC. RnRC/TSMM have horrible hourly capacity, so there's only 3 people-eaters in the bunch.
People say USF/IOA can't fit much more than 10 million/yr, yet DHS can with zero shows, large sections of the park under construction/shuttered, and 5 real attractions?
