Artist registration to participate in the art show

The DemiCon art show is open to all interested artists, including students, amateurs and professionals.

We promote fantasy and science fiction art by helping artists to display and sell their work to convention attendees.

For more information, including PDF registration forms that you can use instead of the online registration, visit the Art Show section of the Venue Areas page and scroll down to the “Information for artists” section.

Art Show Registration Form

If you have any questions or problems please contact artshow@demicon.org.


Dealer room application

The DemiCon Dealer Room has 28 table spaces. We will be holding a juried selection for our vendors. This means that all prospective dealers will need to submit a Dealer Room application to be considered for having vendor space.

We have not yet opened the application process. Check back later to submit your application.

Dealer Application

Our Dealers Room coordinator can be contacted at dealers@demicon.org if you have questions.


Host a room party

If you or your organization are interested in hosting a room party on Friday, Saturday, or both nights of the convention please review our Drinking Policy and Guidelines for Party Hosts.

All room parties must be registered and will be placed on the 5th floor of the hotel.

No parties are permitted anywhere outside the 5th floor.

You must schedule your room party with the room party coordinator before the room block closes.

Room Party Sign-up

If you need anything for your party our room party coordinator can be reached at parties@demicon.org.


Masquerade, cosplay, and Hall Costume participant registration

Part of the fun of any con is the freedom to dress up as your favorite character, or archetype, or as some completely unique and original concept spawned from your own very creative brain. We at DemiCon like to encourage that freedom further by offering you the chance to show off your clever ideas and talented handiwork through our costume contest events.

Masquerade and cosplay

On Saturday, the main stage masquerade and cosplay event lets you thrill our audience with not only your spectacular costume creations, but your skilled (or not-so-skilled – we don’t care, we love just watching everyone try!) mini-performance. More details can be found on the Things to Do page under Masquerade and cosplay.

Masquerade and Cosplay Registration

If you have questions or need more information contact masquerade@demicon.org or join our Facebook Group at https://www.facebook.com/demiconmasqueradeandcosplay/.

Hall Costume

On Friday night, the Hall Costume contest allows you to immortalize your amazing apparel via our fabulous official photographer’s portrait service (it’s free!), while our mystery judges mingle among the attendees to quietly select the best-of-the-best.

Sign-up will take place in person at the convention. For more details go to Contests on the Things to Do page.
