Fear is the secret to happy marriages, lasting friendships, and the final ingredient in numerous madman-created serums. Get a dose with today's Groupon: for $9, you get a Fun Pass to Ghostly Manor Thrill Center, with admission to the Ghostly Manor (up to an $11 value) and Skateworld (a $5 value for admission, and up to a $3 value for skate, roller blade, or scooter rental) in Sandusky (up to a $19 total value).

Proud member of the DAFE Top Ten Walkthrough Attractions and a Rand McNally Top Ten Haunted House, Ghostly Manor Thrill Center employs year-round spooks, elaborate sets, and frightfully effective actors for a tummy-twisting experience. Recent renovations to the manor itself afford a bigger and better maze of horror, with expanded haunts, more attractions, and a fearsome fire-breathing dragon. Amid ghosts, goblins, and ghouls, visitors' uvulas can hula to the sound of their dulcet screams. Skate off the icy adrenaline of terror with admission and skate or scooter rental at Skateworld. Roller skating, blading, or scootering provides fun for every age and panic threshold, along with a quick getaway in the event of a haunted-house uprising. Check the schedule for Ghostly Manor's seasonal hours.

The haunted house is recommended for ages 10 and older.
