Blue Reply button? Anyway, my question—if this is the right place to ask it—is about trying to make a 3-D understanding of 2-D floor plans in the PDF GA book. On what floor is the Exhibit Hall? What is all the solid brown area on Level 200 (page 121 of the PDF)? It looks like the plenary events are on Level 100, Hall F & Swing, and Level 400, Ballrooms. There is no legend that I can see—am I right that S = Stair (seems to have steps drawn), E = elevator, and the human icons are rest rooms? I know that I’ll be hustling from one place to another, so the more I can figure out in advance, the easier it should be when I arrive. Thanks for any help deciphering all this!
