In addition to the scheduled Guest of Honor, TusCon has had a reputation of having many professional writers, artists, and publishers attend the convention.
Among those are Forrest J. Ackerman, Robert Asprin, Keith Henson, S. P. Somtow, David Schow, Dr. Edwin "Buzz" Aldrin, Simon Hawke, Liz Danforth, Judith Tarr, Patrick Nielsen Hayden, and others.
These include a Writers Workshop and contest held in conjunction with the Tucson-Pima Co. Municipal Library, An "adults-only" Midnight masquerade where costumes (or the lack thereof) tended to stretch societal norms, a "Furry Critter Stomp" where a dance floor was littered with a variety of nondescript plush beanbag "critters" and Congoers were invited to dance without concern for foot placement, a flintknapping seminar by Dr. Susan Gleason, and chili served to Convention members during the "Dead Dog Party" on the last day of the Con.
