Fright Dome drew me to Vegas in October. However this will not be happening at Circus Circus Hotel & Resort Casino this year. 

Circus Circus has not released a reason.

"Circus Circus has informed Egan Productions that it will not move forward with Fright Dome for 2018. While we regret this bad news, we are grateful to the people of Las Vegas for supporting Fright Dome over the past fifteen years. We look forward to many successful Halloween events in the future."
