Sorry to bother you-but I have a question. Would it make it easier to reframe the question and ask say, "what are three things that would make conventions easier for you?" instead of making it a formal "what are your access needs?"

As an access services person, I try to think about how different people use and interact with the convention space, and what things would make that interaction easier, or simpler. But, even with guiding documents, like the Geek Feminism Wiki, and guidance from Universal Design experts (http://www.nea.gov/resources/accessibility/pubs/DesignAccessibility.html), I can't think of everything, and so requests really do help.

(and I am worried I am talking too much on here.... sorry!)
