Getting your badge and registration packet

Your registration is picked up at the convention. We do not mail the memberships to you. Remember to bring your Photo ID so you can pick up your badges. If you do not have your photo ID, we cannot give you your badge to attend DemiCon.

You will also be required to show proof of full COVID-19 vaccination or a negative COVID-19 test from no more than 48 hours prior. See our policies for details, including what forms of proof will be accepted.

We reserve the right to adjust our COVID-19 policies and requirements as public health guidance is revised.

At the door registration and pre-registration badge pickup officially opens at 2:00 PM on Friday, May 6, 2022.

Hotel Information

A group room block with special rates is reserved for the convention. The special room rates are:

A Standard Double Room or a King Executive Room is $102 per night + tax.

A Junior or Extended Suite is $132 + tax.

Family or Parlor Suite rate is $162 + tax.

Please make your reservation as soon as possible to ensure you get a room. Historically we fill the hotel. If you wait until the last minute there may be no rooms available. The absolute latest to get a room in our room block is April 13, 2022.

Reminder that if you use your debit card the hotel will put a hold and pre-charge your rooms. This could cause money you think should be there to be unavailable throughout the weekend. Due to this common hotel practice, we suggest the use of a credit card if this would be an issue.

DemiCon is being held at:

Holiday Inn Northwest
4800 Merle Hay Road
Urbandale, Iowa 50322

There are other hotels around that you can stay at if you wish.

The Holiday Inn does allow animals on 1st floor only. They cannot be taken to other levels/floors.

How do I reserve my hotel room?

Option 1)  Make your reservation online using the room block code D22.

Option 2)  Call the hotel directly at 515-278-4755 and ask to be placed in the “DemiCon 33 in 2022″ room block (room block code D22).

  • (Important: Do not call the corporate Holiday Inn 1-800 number. Corporate customer service will tell you that there are no rooms available because they don’t’ understand how the convention room block works. If the front desk at the hotel is busy, there is a chance your call might roll over to the 1-800 number. If this happens, kindly ask that they transfer you back to the hotel front desk.)

Please let us know if you encounter any difficulties making your room reservation.

Dealers’ Room Registration

Dealers’ Room Application

The DemiCon Dealers’ Room capacity is 28 table spaces. We will be holding a juried selection for our vendors. This means that all prospective dealers will need to submit a Dealers’ Room application to be considered for having a space for vending.

Dealer tables are $35 per table (strict limit of 3 tables), and a convention membership will be required for workers at your table.

Dealers’ Room Rules and Guidelines

Permit and Sales Tax: The state of Iowa requires that all dealers collect and remit Iowa sales tax on dealer table purchases. Please have your tax permit with you during the convention as you will be asked to provide this information.

Weapons: All edged weapons and other sharp, breakable, or potentially hazardous merchandise must be displayed in a safe and appropriate manner. Do not sell swords, knives, etc., to minors without the permission of the minor’s parent.

Display: Please display any adult-themed merchandise in a tasteful manner.

Safety: No open flames allowed (e.g. no burning of candles, incense, illudim 348, lit canons, etc.). Do not “flow” your merchandise and displays into the aisles or other dealer spaces.

Sound: Music and video are permitted in your dealer area. However, please keep the sound to a volume that does not annoy your neighbors. If it is too loud, you will be asked to turn it down.

Food Vending: Dealers cannot sell food items because of hotel regulations on corkage and food vending.

Membership: DemiCon membership is not included with your table(s). Every person who will work your table must have a membership, and badges must be worn at all times.

Set-Up and Tear-Down: You must vend all three days of DemiCon. You must be set up and ready for business on Friday at 2 p.m. and continue to conduct business during all of the Dealer’s Room hours until 2 p.m. Sunday. You cannot dismantle your tables until Sunday after 2 p.m.

Business: 2 pm – 6 pm

Host a Room Party

If you or your organization is interested in hosting a room party on Friday, Saturday, or both nights of the convention please review our Drinking Policy and the below guidelines.

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.

Guidelines for Party Hosts

The legal drinking age in Iowa is 21.   This means that your birthday must be on or before May 6, 2001, in order for you to consume alcohol.  Minors caught with alcohol or adults caught serving alcohol to minors need to be aware of the consequences of their actions.  Please drink responsibly and act accordingly.

When posting signage for your party please use blue painters tape and be mindful not to damage the room or its contents.

If you have any issues, questions or concerns during your party, look for the roaming Rangers (identified by the bright yellow/green vests) or the Room Party Department Head.

Please post or otherwise provide information regarding potential allergy issues (nuts, etc.).

Masquerade and Cosplay 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 Contest

On con 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 Programming page under Masquerade and Cosplay.

If you have questions or need more information contact or join our Facebook Group at

Hall Costume Contest

On con Friday, 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.

For more details go to Contests on the Programming page.

Request Pro Invitation or Suggest a Pro Guest

We have many local, regional, and national professionals that attend DemiCon. They contribute to many areas of the convention, such as the art show, the music venue, and programming. Professional guests that contribute in this way may be eligible to be featured in our programming book, as well as receive a free membership to the convention for themselves and a guest.

If you would like to be considered as a professional guest, or if you know a professional that we should invite to DemiCon 33, please fill out this form to let us know.
