Cancelled - TERRIFICON

After a great deal of consideration due to COVID-19, this year’s TERRIFICON event at Mohegan Sun has been cancelled and will return on July 30–August 1, 2021. Refunds are available at point of purchase.

EXHIBITORS: For those artists and dealers who purchased spaces for this year, your paid spots are secured at this year’s rate and will automatically carry over for TERRIFICON 2021. If you would like to cancel your space and obtain a refund, you can do that as well. Simply contact with your business information to begin the process. Please note, that if later on you change your mind and decide that you do want to return for the 2021 event you must submit a new application for the space(s), if they are still available. 

Please Note

*Subject to price increase on day of event. All weekend passes include early entry (30 minutes) on all days.

**Two free with one paid adult admission.

IMPORTANT COSTUME INFORMATION: Costumes will be permitted in the Convention Center, after parties, hotel, lobby and pre-function area. However, wearing a mask, make-up or any type of face coverings is NOT allowed in the gaming areas.  Decisions as to what constitutes a mask will be made by Mohegan Sun's gaming personnel, whose decisions are final.
