Ghosts roam the earth to complete unfinished tasks, such as making peace with a loved one or picking up the dry cleaning. Witness the errands of the undead with today’s Groupon: for $18, you get a haunted outing at Madame Tussauds Las Vegas (up to a $36 total value) located on the moving walkways in front of the Venetian Resort Hotel Casino. The outing includes:

• One ticket to After Dark at Madame Tussauds (up to a $20 value)
• A keepsake photo (a $16 value)<p>

After Dark is held October 21–23 and October 28, 29, and 31 from 9:00 p.m. to midnight. Madame Tussauds recommends customers attend After Dark October 21-23 for shorter entrance lines.

Madame Tussauds wax museums trace their roots back to the 1770s, and their eerie history continues in the Las Vegas corridors where the Travel Channel’s Ghost Adventures crew has tracked down paranormal activity. During the day, dozens of lifelike wax sculptures bring Hollywood stars, sports heroes, and world icons to life, and at night, guests 12 and older venture into the shadows of After Dark, where spectral figures and living fiends lurk among the wax figures. For 30–45 minutes, a single flickering light guides visitors as they wander among the figures, trying to divine which are waxen and which are masked actors waiting to pounce on them as a grammarian pounces on misplaced modifiers. A keepsake photo commemorates the night of terror more conveniently than trying to capture screams in a bottle.

Though Madame Tussauds Las Vegas sometimes features a discounted price online, this Groupon still offers the best deal available.
