For over a year now, I have been traveling and going to professional conferences as a person with a disability, a wheelchair and crutches user. Abilities and disabilities vary wildly. My own issues are most often bathrooms, distances, exhaustion, and stairs. I am less aware of issues and solutions for people with visual impairments and for the deaf or hearing impaired community; I apologize for not addressing those issues here. If you have mobility issues and wonder about the accessible geography of the conference, I have a ton of information!
