Fan reception to the convention was mixed, with many con participants voicing that they were very unhappy with the way things were run. Many con-goers reported sessions not lasting their full-time, as well as the con using volunteers for security. The AV Club panned the convention overall, commenting that it was poorly thought out and that the merchandise area gave "the impression that Twicon exists solely to get impressionable fans to pay for crap". Many fans noted that even the stars guesting at the convention appeared to be annoyed at the treatment given at the con, though TwiCon representative Becky Scoggins insisted on the TwiCon forums that none of the stars present voiced any complaint over their stay at the con.
Citing both "competitive pressures" and "the persistent nature of the economic downturn", TwiCon Partners LLC announced that it would cease operations on March 13, 2010. Organizers said that "non-refundable deposits" and payments to "professional service providers" left them with insufficient funds to "cover the next round of deposits due to host the event". This cancelled TwiCon events planned for Ottawa in June 2010 and Las Vegas in late July 2010. (The Ottawa event was originally scheduled for Toronto but was forced to relocate due to the 2010 G-20 Toronto summit.) No official statements were ever released to the convention website as to the availability of refunds for ticketholders, although Scoggins claimed that her company had no control over the finances and that letters pertaining to the availability of refunds were forthcoming.
