If you've ever stood in a church parking lot in late October watching a hundred kids in costumes go car to car, you already know why trunk or treat took over. It's contained. It's lit. Parents can see their kid the whole time. And the candy comes fast enough that nobody melts down on a school night.
We deliver inflatables to a lot of these events every fall, from small church lots around Conyers and Covington to bigger school and HOA nights out in Gwinnett, Henry, and Cobb. The ones that run smoothly usually got a few boring things right early, and the ones that turn stressful usually didn't. Here's what tends to work.
Walk the lot before you plan anything else
Your parking lot decides your event. Not your Pinterest board.
Go stand in it a few weeks out and count what you actually have. How many spaces can you give up to decorated trunks? Where will families park once those spaces are gone? Is there a spot near the entrance that pulls people in without blocking the walkway?
Most organizers set trunks in a U shape or a single long row so kids move in one direction and come out the other end. A circle looks nice in photos but tends to jam up in the middle once strollers get involved. Leave the middle of your lot open, and give yourself a clear lane for anyone who needs to leave early.
Car themes volunteers can finish in an afternoon
The best trunks aren't the most expensive ones. They're the ones somebody finished. Simple themes that hold up:
- Fishing pond, a tarp over the trunk and a pool noodle rod, kids "catch" a candy bag
- Farm stand with hay bales, a couple of pumpkins, and burlap
- Under the sea with blue streamers and paper fish
- Campsite with a fake fire, camp chairs, and s'mores wrappers
- Movie drive-in, cardboard screen and popcorn boxes
- Space with black fabric and foil stars
Send your volunteers the theme list when they sign up, not a week before. People who know their theme in September actually decorate. People who find out in late October show up with a bowl of candy in an undecorated hatchback, which is fine, but you'll want a couple of backup trunks planned either way.
One trunk should be a no-costume, no-noise, low-key option. Some kids get overwhelmed by a strobe light and a fog machine at the same booth, and having one calm car near the end of the row gives them somewhere to land.
Candy math and the trick nobody tells you
Figure roughly two pieces per kid per trunk. So 100 kids and 12 trunks means each volunteer needs somewhere around 200 pieces. That's more than most people bring on their own, so plan a church or PTA candy drive in the first week of October and split it evenly the night before.
The trick: hand out candy from a bowl held by the volunteer, not from a table kids reach into. Bowls empty slower, hands stay cleaner, and you avoid one kid clearing a trunk in ten seconds.
Set aside a small allergy-friendly bin too. Stickers, glow bracelets, and little bubbles cost almost nothing and mean every kid on your lot leaves with something.
Give kids something to do when the trunks run out
Here's the part that catches first-time organizers off guard. Trunk or treat itself takes about 25 minutes. A hundred kids will clear a dozen trunks faster than you think, and then you've got a parking lot full of sugared-up children and 90 minutes of event left.
That's why most of our fall calls are for exactly this. A bounce house or an obstacle course gives kids somewhere to go after the candy loop, which buys parents time to talk, eat, and actually enjoy the night. Units like The Atrium bounce castle work well for the younger crowd, and RampageZone is usually where the older kids and middle schoolers end up.
Put the inflatable at the far end from the trunk row. Visible from the entrance, but not crossing the candy line. Kids will find it. If your event draws a few hundred people, two units split by age beats one crowded one, since long lines sour a good night faster than anything.

Power, and what to do about a lot with no outlets
Inflatable blowers run on regular household power. If there's a standard outlet on the building within reach of an extension cord, you're set. Parking lots are the one place that trips people up, since the nearest outlet can be an entire building away.
If that's your situation, a generator solves it. We wrote up how that works in do you need a generator for your bounce house, including what to check before your event day.
Safety on a dark lot
Two things matter more at a trunk or treat than at a backyard party, and both come down to it being dark and full of cars.
Close the lot to traffic before the first family arrives. Not at start time, a solid 30 minutes before. Park a volunteer at the entrance with a vest and a flashlight, and have another one at the exit. Every drop-off after that point happens at the curb.
Then light your walking paths. String lights, battery lanterns, or just the building's floodlights aimed at the row. Costumes are dark, kids are short, and October dusk in Georgia comes earlier than people expect.
If you're running an inflatable, assign a volunteer to it for the whole event, not just the first hour. Shoes off, jewelry off, no food inside, and a reasonable count of kids at once. Our bounce house safety tips post covers the rest, and it's a quick read to forward to whoever is working that station.
Have a rain plan on the calendar
October in metro Atlanta can hand you a 75 degree evening or a cold drizzle, sometimes in the same week. Pick a backup date now and put it on the flyer. Grass fields turn to red clay soup fast around here, which is one reason a paved lot is the better home for a trunk or treat anyway.
If rain moves in, a fellowship hall or gym can hold the trunk row using tables instead of cars. It isn't the same, but it beats canceling on a hundred families the morning of.
Booking your October date
Fall is our busiest stretch, and October Saturdays fill up weeks ahead. If your church, school, or neighborhood already has a date, that's the piece worth handling now, before the good weekends are gone.

Frequently asked questions
How many decorated cars do we need for a trunk or treat?
A rough rule most organizers land on is one trunk for every 8 to 10 kids you expect. Fewer than that and lines back up, more than that and the lot feels empty. Recruit a few extra volunteers, because some always drop out the week of.
Can you set up a bounce house in a church or school parking lot?
Yes. Grass, asphalt, and concrete all work fine, and we anchor the unit appropriately for whatever surface you have as part of setup. Just walk us through the space when you book so we can pick the best spot.
Do you provide a certificate of insurance for church and school events?
We can. A lot of venues and school districts ask for one before an outside vendor sets up on their property, so tell us early and we'll get you the documentation.
What does an inflatable cost for a fall event?
Rentals start at 150 dollars a day, and delivery, setup, anchoring, and teardown are included within 35 miles of Conyers. Call (404) 480-2645 and we'll talk through what fits your crowd size.
Do we need power in the parking lot?
The blower runs on regular household power, so a standard outlet within reach of an extension cord is usually all it takes. If your lot is far from a building, a generator covers it.
How early should we book an October date?
October Saturdays are the busiest of our year and go weeks in advance. As soon as your date is set, reach out through /contact and lock it in.
