Trailer Park After Dark is the Halloween party venue San Diego costume crews keep asking for — an underground, trailer-park-themed bar in the Gaslamp Quarter built around three era-themed private trailers, each one a backdrop your costume was never going to get in a bar crawl line on 5th Avenue. At 835 5th Ave, Lower Level, the 60s, 70s, and 80s trailers aren't decorated for one weekend a year. They're permanent, decade-accurate rooms — your group gets an actual set, not a folding table with a rubber skeleton taped to it.
That's the one thing no other themed bar San Diego has on Halloween weekend: three different eras, three different backdrops, one bar. Pick the trailer that matches your group's costumes and text ahead — the rooms go fast once October hits.
Why the Trailers Beat a Regular Bar on Halloween
Most Halloween party venue San Diego options are a normal bar with a fog machine plugged in for one night. TPAD skips the seasonal decorating because the trailers are already themed year-round, down to the wallpaper and the light fixtures. A group dressed as a 70s disco crew doesn't need string lights hung specially for them — the 70s trailer already has them.
It's the difference between a costume photo taken in front of a bar and a costume photo taken in front of a set. Groups notice. So does everyone scrolling through the photos the next morning.
Three Trailers, Three Different Costume Party Nights
The 60s trailer runs cleaner and quieter — a good pick for a costume group leaning vintage. The 70s trailer is the one most groups ask for by name: rooster wallpaper, teal vinyl booths, warm string lights, and room for up to 25 guests, which makes it the call for a bigger costume crew. See the room details on the 70s trailer page.
The 80s trailer leans into the decade's loudest visual instincts, and for a costume party built around neon and shoulder pads, it's one of the only bars with private rooms San Diego has that actually matches the theme instead of fighting it. Check out the 60s trailer and 80s trailer pages to compare all three before you book.
How Far Ahead to Book for Halloween Weekend
Halloween weekend in the Gaslamp Quarter fills fast, and private trailers get booked in the order they're requested — not held for a maybe. Text (619) 889-2312 at least two to three weeks before October 31 if you want your first choice of trailer for a Friday or Saturday night.
Weeknight availability opens up more depending on where Halloween falls that year, but the Friday and Saturday nights closest to the date go first regardless. If your group already knows which trailer it wants, say so in the first text — it saves a round trip.
Group Size and What's Included in a Private Trailer Booking
The 70s trailer seats up to 25 guests. The 60s and 80s rooms work better for smaller costume crews who still want the room to themselves. Booking gets your group the whole trailer, not a roped-off corner of it — nobody else gets seated at your tables for the night.
A private trailer booking includes the full food and drink menu for the duration of your reservation, the decade-themed room as your group's home base, and direct text access to TPAD if your headcount or timing changes. Read more on the private events page, or see the full private trailer rental San Diego guide for the full walkthrough.

Halloween Weekend in the Gaslamp Quarter — Why a Private Room Matters
Halloween spending nationally hit a record $13.1 billion in 2025, according to the National Retail Federation, with per-person spending climbing to $114.45 — money going toward costumes, parties, and nights out, not just candy at the door.
Nearly eight in ten U.S. adults planned to celebrate Halloween in 2025, and PwC's consumer research found Gen Z and millennials were the age groups most likely to throw or attend a party — exactly the crowd that fills the Gaslamp Quarter every October 31. Gaslamp Quarter Halloween means bar crawls, costume-crowd sidewalks, and a line at the door of every open-floor bar within six blocks. A private trailer skips all of it — your group already has the room.
The Food and Drinks for Your Halloween Party
Start with the Ahi Nachos. They've reached near-cult status on the menu — the dish first-timers didn't plan to order and end up posting about anyway. It's the right move for a group settling into a trailer for the night while the first round of drinks comes out.
Drinks are priced the way a bar that wants you to come back prices them — cheap drinks that actually taste good, not a Gaslamp markup because it's a holiday weekend. TPAD was named Yelp's #3 Most Outrageous Restaurant in America for 2026, and the full story behind that ranking is on the blog if you want the details before you book.
Frequently Asked Questions
How far in advance should I book a trailer for Halloween weekend?
Two to three weeks out is the safe window for Friday or Saturday nights near October 31. Text (619) 889-2312 as soon as your group has a date — trailers are confirmed in the order they're requested.
How many people fit in a private trailer?
The 70s trailer seats up to 25 guests. The 60s and 80s trailers are better suited to smaller costume crews. Confirm your headcount when you text so the right room gets held for you.
Is there a minimum spend to book a trailer for Halloween?
Booking terms can vary by night, and Halloween weekend is no exception. Text (619) 889-2312 to confirm current minimums before you commit — you'll get a straight answer, not a runaround.
Can we wear costumes with masks, props, or oversized pieces inside the trailer?
Best confirmed directly when you book, since trailer space and doorways vary by room. Text ahead and describe your costumes — TPAD will tell you what works and what to leave in the car.
Location, Hours, and Getting to TPAD on Halloween Weekend
Trailer Park After Dark is at 835 5th Ave, Lower Level, San Diego, CA 92101 — underground in the Gaslamp Quarter, San Diego's nightlife district packed with more than 100 restaurants, bars, and clubs across 16 blocks. That density is exactly why a private room matters on Halloween weekend — everything around you is at capacity.
Open Thursday through Saturday from 5pm (Thursday last call 12:30am, Friday–Saturday last call 2am), and Tuesday–Wednesday from 8pm. Closed Sunday and Monday. Rideshare is the practical call for Halloween weekend — Gaslamp parking and street closures make driving in a costume more trouble than it's worth.
