Lol, you people have no idea what your talking about. Yes its ok to wear your suit at other cons and if its a partial you won't overheat unless your a colossal fatass.Just wear a hydration pack(camelpack)and you'll be fine. I go to other parties and cons and havnt had any problems. If your running around in suit and acting like a jackass and pissing people off, then yeah you might run into problems so don't do that.
I went to PHX comi con and had a lot of issues with patrons there. I got sexually and physically harassed. One dude bit me on the back of the head.
