Decongestant 5

Roller skate mascot

It's the fall convention from Mnstf. It will be Oct 7–9, 2022. It will be at the Hilton Bloomington (3900 American Blvd), Minnesota.


Decongestant 5 was originally scheduled for Oct 2–4, 2020. As a primarily-social event, that wasn't going to happen under the Stay Safe MN plan, so we rescheduled for September 24–26, 2021. Then there was the Delta variant. Although the con would have been legal, our survey of the potential membership showed that very few people would have come. Rather than hold a con for 15 people, we postponed again.

Your 2020 or 2021 registration

If you registered before either of the postponements, you are still registered. If you'd prefer a refund, write to; we can do that too.

COVID mitigations

As of this writing (April 2022), we're going to hold off on making policies for vaccinations, masking, distancing, etc. We just don't know what things will be like in October. But if you buy a membership, you're agreeing to follow whatever the rules turn out to be. If you don't like the rules, you can transfer your membership, but you cannot have a refund.

What's Decongestant 5 going to be like?

Decongestant 5 is a small science fiction and fantasy convention geared primarily towards relaxation. There will be good food, music, gaming, a teen room, a bit of programming, and whatever else you bring to it. If you were at any of the earlier Decongestants, say 4, you can expect pretty much the same thing.


This year, for the second time, we are partnering with ARCANA, a convention "Celebrating the Weird, the Macabre & the Dark Fantastic". In addition to our usual 3/4 track of fallcon programming, we will also have a track of ARCANA panels and movies.

Directions to the hotel and airport shuttle information.

What space does the con have?

We have a cluster of small-to-medium-small rooms on the 2nd floor. One is a suite, and the rest are function-space-type rooms. This is an expandable con. If you want to run a large game, create a new department, or have some other cool idea, let us know.


We have one, or possibly a bit more than one, track of fairly light programming and films which will give you something structured to do if you want that. We don't exclude the possibility of heavy programming if there's interest in that.

Contact us if you'd like to schedule something.

Teen Room

There will probably be a teen-run teen room! To be determined!

Child Friendly

Decongestant is family and child-friendly, so please bring yours! However, we don't have child care or specific children's programming (we're just not big enough for that).

There will be a dedicated gaming room available 24h during the convention.


There will be space available for musicians after programming ends all three days.

There will be a consuite. For the uninitiated, this is a room with snacky food and drink (included with your membership) and social space available during all reasonable hours. There will be a fair amount of food here, but it shouldn't be counted on to feed you three meals a day.

We may have optional organized dinners Friday and/or Saturday. To be announced.

Art show/craft swap

There is no formal art show this year, but you are welcome to bring art for display or to sell. There will also be table space for freebies, craft swapping, etc. Label your objects clearly, especially if they are not meant to be taken freely!


3D mascot

Decongestant 5 is a small con with minimal programming and minimal financial resources. Panels and other activities are expected to be reasonably accessible by virtue of being very small. With this in mind, if you anticipate needing accommodations in order to enjoy the con, please contact us and we will see what we can do.

Code of Conduct

You should read the code of conduct.

Want to be Guest of Honor?

You can be our Sucker Guest of Honor for the low price of $500, first come, first serve. You'll get your name in lights, the chance to make a speech (or avoid making a speech), and it will fund us to rent an additional social room at the hotel for the con. Just select the Sucker Guest of Honor option on the registration form below!

What are those fees? They cancel out what PayPal charges so that, for example, we get the full $50 for a $50 membership. There is no fee for paying by cash or check, because our bank doesn't charge us to deposit those.
