The cosplay I'm building for next year can contract to navigate ADA door requirements so I'm not worried about fitting through entry doorways.
But once you're INSIDE the Hilton, Marriott, Hyatt, etc. what is a reasonable target height clearance to remain under when it comes to hallways, interior archways and the like?
I'm guessing the approach hallways in the Marriott that lead to the sky bridges would be a good target but I don't know how high those ceilings are.
Any suggested max target heights from cosplayers who've had extra tall/large cosplays at Dragon Con?
