About this Event
A Hamilton Halloween: The Mystery of Room 231
An adults-only Halloween experience where cocktails, costumes, and a century-old mystery collide.
The centerpiece of the night is The Mystery of Room 231—an immersive, hotel-wide mystery game that sends you searching for hidden evidence, investigating four unsolved murders, cracking the combination to a locked safe, and uncovering the chilling truth behind a room that no longer exists.
The evening begins with Cocktail Hour from 6:00–7:00 PM, featuring vendor-sponsored selections and specialty cocktails. Grab a drink, mingle, explore the hotel, and get into character—the mystery is about to begin.
At 7:00 PM, investigators gather on the Amenity Deck for the opening video and official game instructions. Then you’re turned loose. Follow the evidence, connect the clues, unlock the safe, and see if you can solve The Mystery of Room 231.
Solve the mystery correctly and you’ll earn entry into the GAME WINNER RAFFLE, for one seriously killer Hamilton experience: a private five-course Chef’s Dinner for two with wine pairings, an overnight stay, champagne waiting in your room, valet parking, and special room amenities.
And don’t just come ready to investigate—come dressed to K*ll. Our Halloween Costume Contest will award prizes for 1st, 2nd, and 3rd place, so bring your best. Between clues, grab another cocktail, strike a pose at the Halloween Photo Booth, and enjoy a night of music, drinks, dancing, costumes, and Halloween mischief.
At 9:00 PM, everyone comes together for the big reveal as we announce the Game Winner Raffle winner and our 1st, 2nd & 3rd Place Costume Contest winners.
🔞 ADULTS ONLY • 🎭 COSTUMES ENCOURAGED • 🔎 CURIOSITY REQUIRED
