The HELIOsphere MarketSpace provides a varied shopping experience. Our attendees are fans of science fiction and fantasy, but we also have readers of literary hard science fiction, writers in the genre, and science enthusiasts.

What are the size of tables and what will they cost?

Please read this FAQ if you are interested in vending at HELIOsphere. You will be expected to abide by the information and rules presented here if you apply and are accepted into the MarketSpace as a HELIOsphere dealer. You will be further required to be compliant with HELIOsphere’s Code of Conduct and COVID policies that can be found on our website

HELIOsphere will have tables available that are 6’ x 2.5’ and come with 2 chairs and 1 tablecloth. If you have specific needs please note that in your application where prompted along with any access requests. We will do our best to fulfill them. 

Table prices are: $45 for 1 table, $80 for 2 tables and $125 for 3 tables. You may request any number of tables on your application form and we will try our best to accommodate those requests. All requests for space are subject to the MarketSpace Team’s approval.

Do the tables come with memberships?

Tables do not come with memberships and HELIOsphere memberships must be purchased as a separate item when you pay for your space. There is a special membership rate of $60 for dealers and you will be able to select that rate when you pay for your tables. If you do not receive table space(s) your membership(s) will be refunded upon request. Everyone who will be working at your table must have a membership. You can get a membership at the Membership Page and use promo code dealerdisc for the rate.

Will there be electricity and will it cost extra?

Electricity will be provided by the hotel. Plan to use UL listed devices. While we have some supplies, if you will be using electricity you should bring your own extension cords and gaffer tape to secure electrical cords. You are not guaranteed a wall space where outlets are located and you will not be permitted to run extension cords across aisles without taping them down. If you have specific electrical needs, please be sure to list them in your application so that we can include your needs into our layout.

Will there be Internet connectivity in the MarketSpace Room and what will it cost?

The hotel provides free Internet in the lobby.  If you require Internet connectivity to conduct business please let us know with your application.

When do applications close and when do acceptances go out?

Applications will close on April 1, 2024. Acceptances will go out on or about April 15, 2024. Payment is required within 3 days of acceptance or your space will not be held. All acceptances are at the discretion of the MarketSpace Team and if you are not accepted (most likely because we sold out) you will be offered space on the waitlist or a refund. Please do not wait for an acceptance to reserve a hotel room. You can always cancel the hotel reservation if you are not accepted and do not choose to attend.
