It looks fairly similar in shape to Energy’s old maintenance bay. I’m starting to wonder if they only tore down the old one to allow easy access for construction vehicles and equipment, and now they’re just rebuilding it.
The whole perimeter of GotG needs a thick berm of trees when complete. The current tree line is just too bare on the left side of the EPCOT entrance. The "I cant see it blue box" is bad enough. I at least hope there is a plan to obscure the back area more at ground level view.
