This info came up over in the fascinating Permit thread that
@SSG maintains. But it's an interesting piece of info, so deserves to be quoted over in this thread too.
The permit for the Alcatraz (Battle Escape) E Ticket warehouse building reveals the size of this monster. 165,565 square feet!
Which begs the question... how big is it? It's bigger than Indy's warehouse building, at a measly 54,000 square feet thanks to some research by
@NobodyElse!
Judging by aerial photographs and leaked maps of Star Wars Land, 165,000 square feet appears to be simply the footprint of the building on the land. The Alcatraz building footprint is roughly three times the size of the Indy warehouse footprint. In fact, you could fit both Indiana Jones and Pirates of the Caribbean inside the Alcatraz building footprint, with some room to spare!
This Alcatraz building is massive. A footprint of 165,000 square feet, plus a height much taller than Indy or any other Disneyland building except the Matterhorn. And as we can see from recent construction, Alcatraz has two 25+ foot tall floors of space for ride showrooms, plus a deep basement and at least one part of the building where the AT-AT's are that use the entire 75 foot tall space.
While we all know this is going to be huge, especially those of us who have seen it in person from the parking structure (pictures warp the scale quite a bit), I don't think it has dawned on us just how giant the scale and scope of this one ride is going to be. Indy + Pirates < Alcatraz.
This is certainly unprecedented for Disneyland, perhaps for any theme park anywhere.
