Nightmare on Third Street @ W Hotel

If an ultra-modern lounge is more your vibe, don your slutty Kellyanne Conway costume for a fete with a full-service bar, festive holiday fare, and electro-pop beats. Valet and garage parking will be hella scarce, so take a Lyft. // 9pm to 2am October 31st; W Hotel, 181 3rd St. (SoMa); tickets ($10-$30) are available at sfhalloween.com.

Costumes and Cocktails Halloween Yacht Party @ Hornblower's SF Spirit Yacht

You could go for the alliteration alone, but setting sail with 500 or so other ghouls for a dance party-slash-sail with Hornblower certainly doesn't suck.

Monster Bash @ USS Hornet

Good thing the parking is free because you'll have to pay for your own drinks at the Monster Bash aboard the USS Hornet.

Don't let the sugar-coated name lull you into a sense of comfort. Coming off a successful event last year in L.A., Brown and Lemonade's Haunted House Party arrives in the Bay Area with a three-story haunted mansion—four frightening rooms filled with live-action scare tactics. Once you've been scared senseless, you can sweat it off dancing to surprise DJ guests. // 10pm-3am, October 27th; 1015 Folsom St. (SoMa), 1015.com; tickets ($20-$25) are available at Eventbrite.

Black Light Art Show's Encore Halloween Party @ Studio 23
