Setting up on pavement, grass, or indoors for a trunk-or-treat
Measure the open space you can actually give us, not the whole lot. Each inflatable needs extra room around it for the blower, the anchors, the way in and out, and an adult watching the line. Keep an emergency lane open, too.
On pavement, the first question is how that exact unit gets anchored. We only use sandbags or ballast when the manufacturer allows it, and a parked car or weights from home won't do the job. Indoors, measure the height under the lights, beams, and fans, and make sure the unit can get through the loading door and around any hallway corners. Our guide to bounce house on concrete, grass, or indoors is worth a read before you pick a spot.
If it's at a school or church, check with them on where we can unload and what time we can get in.
