Beginning Sept. 21, Universal Orlando’s Halloween Horror Nights returns for 25 nights of intense Halloween fun and terror. This year, once guests step inside Halloween Horror Nights, they will not be able to escape the horror that awaits them, including terrifying haunted houses featuring some of the biggest names in pop culture — like AMC’s “The Walking Dead” and Silent Hill. And, with a completely reinvented street experience, “scarecators” will seek them out no matter where they turn. The fun includes trying to escape Penn & Teller’s nuclear ooze-covered Las Vegas wasteland, and coming face-to-face with twisted concepts pulled straight from legendary shock rocker Alice Cooper’s most popular songs. Halloween Horror Nights runs Sept. 21-22, Sept. 27-30, Oct. 4-7, 11-14, 17-21, 24-28 and 31. (http://www.universaltravelagents.com)
