^ Dude, I'm awesome with spatial perception and all, but that place confused the hell out of me the entire time I was there. It was only a couple years after leaving Berklee that I saw floor plans for 150 that I was finally able to make sense of it all, but to this day it's still a clusterfuck trying to navigate it in person.
It's one of those places that no matter how often you're there you always have to "feel" your way through it, and cross your fingers you end up where you need be.
