MarsCon 2023 Registration

MarsCon 2023 Registration Rates
Through 10/31/2022 EXTENDED!
Through 2/2/2023
At the Door (2/3/2023 through con)
Teen/Adult $45.00 $55.00 $70.00
Child (6-12) $25.00 $30.00 $35.00
There is no registration charge for children under six years of age. We are happy to provide badges for this age group upon request, however they don’t need to wear badges.
Supporting $30.00 $35.00
† Supporting members pay a reduced rate through 2/2/2023 to hold memberships and then complete the purchase by paying an additional $25.00 at any time up to and including at the door.
Sponsor ‡ $80.00 $80.00 $80.00
Sponsors don’t get any perk in particular — at least nothing that’s going to cost us money. They do get the smug satisfaction that comes with knowing that some extra yummy snack in the Consuite… or perhaps another mic for Mainstage… was made possible by their contribution. Our assumption is if you’re donating extra money to MarsCon you want us to spend it on making the con better.
Party Host (x2 per party) $35.00 each $45.00 each n/a
Party Host Discount — We offer a discount for the first two party hosts per party. Party hosts must include at the same time a Party Request form along with two registrations. NO EXCEPTIONS. The Party Host discount offer is valid until 2/2/2023 - after that At The Door rates apply.

Single Day Pass rates are announced
Friday Only Saturday Only Sunday Only
Child 6-12$15.00$25.00$15.00
Single Day Passes will be available at the registration desk (or the Bridge if registration is closed).
Friday and Saturday Single Day passes are good through 6:00 am the following day. Sunday Single Day passes are good through the end of post-convention parties.

To buy with cash...

We accept cash at MarsCon parties at various cons throughout the year. Tell the people running the party room you want to register for MarsCon. They’ll get you all set up. Of course we also gladly accept cash at the door.

To buy with a check...

We also accept checks at MarsCon parties. Or, you can print out our 2023 registration form and send it along with a check. Our mailing address is:
P.O. Box 21213
Eagan, MN 55121

Online Registration Woes?

We have used Square to process credit cards for several years, and it has worked wonderfully. Until this year. Now there are sporadic periods where you will see "Not Available" instead of "Add to Cart" - troubleshooting so far says this failure doesn’t seem to depend on browser used, presence or absence of cookies or - well - a lot of things. The Square site does seem to heal itself from time to time, so perhaps trying again in a few minutes may help.
If all else fails, send an email to with the number(s) and type(s) of registrations you want. We can generate a custom Square invoice for the total - a method that has been working successfully.

To buy with a credit card...

MarsCon uses Square to process our credit cards. Pick the membership type(s) you want, and make your purchase. Square accepts Visa, Mastercard, AmEx or Discover, and there is no need to sign up with Square to make the occasional purchase. Once you have made your purchase please drop an email to with real-world names and desired badge names for everyone in your party. Otherwise we will have to track you down for the info needed to prepare your badges.

To buy at the door...

Bring your credit card, checkbook, or fistful of cash to the registration desk at MarsCon 2023. You can save a couple minutes in line by filling in a copy of the registration form in advance. People arriving late at night will be able to register or pick up badges in the Bridge. The Bridge, however, will not be set up to accept credit cards, so if you want to go that route to register try to arrive during daytime or early evening hours.
