Excellent! This is making me very confident. I already built the flamethrower, and it has a shoulder strap which goes underneath the tank, which can be easily unclipped.
The con is this weekend, and it's my second year attending. For the most part, there are no tiny spaces that are hard to navigate. I'm also going to stay away from the dealer's room as much as possible...
According to the con rules, I'm allowed to have it! I even emailed the show manager about it, and I'm going to print his email out to snub anyone who says I should leave.
Thanks for the advice, everyone. Definitely helpful for making sure my mental checklist is complete.
