Haunted Halloween Ball, Chicago

As one of Chicago's biggest costume parties, the Haunted Halloween Ball combines the lavish experience of a VIP nightclub and hotel gala with the terrifying ambiance of a haunted house. Each year the spooky bash invades the Congress Hotel—which voted one of The Most Haunted Hotels in the World by USA Today—and transforms its 20,000-square-foot ballroom into a nightmarish scene overrun with zombies and ghouls. Costumed go-go dancers, zombie cocktail servers, and vampire bellmen roam the haunted ballroom floor as top DJs fill the air with dance beats. Haunted Halloween Ball also invites its guests to go all out with their costumes with winners receiving $3000 in cash and prizes.
