This Halloween weekend, take your party on the water for the spookiest cruise around, Nightmare on Lake Michigan. Grab a group of your best friends, come dressed in your sexiest, scariest or funniest costumes and get ready for a monster mash aboard the swanky Mystic Blue Yacht. You’ll board from Chicago’s iconic Navy Pier, then set out along the lakeshore, taking in the gorgeous views of the skyline at night. Hit the dance floor as the live DJ spins beats and the multiple cash bars keep the drinks flowing.  Goldstar shows comp tickets for the October 30th cruise.
