Some nights you remember. Some nights leave a mark. 
This Halloween, prepare to be Bitten by the Bay at the 4-star Hyatt Centric Mountain View for a night of cocktails, costumes, dancing, prizes, and plenty of opportunities to meet people.
Singles, couples, and friends are all welcome. And because many of you are coming single, our VIP singles experience returns as the VIP Singles Sanctuary Lounge—a private, low-lit lounge exclusively for singles.
This isn't simply another Saturday night at a crowded bar. It's a six-hour Halloween experience with multiple spaces, each offering a different way to enjoy the night.
For more than a decade, we've produced large Halloween Costume &amp; Dance Parties in the Bay Area, with past themes including Bewitched by the Bay, Ghosted by the Bay, and Zombied by the Bay.
This year, prepare to be Bitten by the Bay.
THE HALLOWEEN EXPERIENCE
Your night begins in the Twilight Lounge, our spacious social area. Check in, grab a drink, check out the costumes, and start meeting people.
Then enter the darkened Crimson Ballroom, illuminated with red backlighting and special Halloween effects. This is the heart of Bitten by the Bay—home to our dance floor, costume contest, bar, and VIP Singles Sanctuary.
And once you're inside, be careful.
This is where most of the biting happens.
DJ Dave X is back! He's kept our Halloween and NYE dance floors packed with dance hits, throwbacks, and party anthems. No dead dance floor.
Want somewhere you can actually have a conversation? Weather permitting, step outside to the Moonlight Terrace at View on Two, the Hyatt's spacious outdoor patio and bar. Enjoy the night air, admire the costumes, and mingle away from the music.
VIP SINGLES SANCTUARY
Coming single? We've created a space just for you.
Our VIP Singles Sanctuary is a private, low-lit lounge inside the Crimson Ballroom reserved exclusively for singles. Mingle, meet other singles, enjoy complimentary appetizers, or simply take a break from the dance floor.
VIP admission includes General Admission plus: • Exclusive Singles Sanctuary access • Private, low-lit environment • Limited seating • Complimentary appetizers while supplies last
VIP tickets are limited.
DARE TO TAKE A BITE?
Two specialty Halloween cocktails will be available for purchase:
🩸 The First Bite 💋 Bitten &amp; Smitten
