Something that didn't click with me in the pictures until I actually drove into the garage was how high the clearance was on at least the first floor. I don't know if it's just for construction, or if it will continue once Disney Springs is all open, but there was a full sized semi-truck pulling into the parking structure when I was. It drove down through to the end of the 1st floor and stopped, my guess was either to get directions or to unload right there.
I'd hope that it isn't a permanent loading dock area, or at least not the main one, once this finishes, because it slowed down entering the parking structure. The fact that they built it large enough to handle this though makes me think that they plan on trucks entering it enough to make it worth designing it that way in the first place.
