Neighborhood Halloween outdoor movie night: one porta potty enough for about 120 people on the HOA lawn?
Our HOA is doing a free Halloween outdoor movie on the common lawn this Saturday. We are expecting around 120 people (lots of kids plus parents) for about three hours, starting at dusk. There will be popcorn and cider, no alcohol, and the clubhouse bathrooms are a long walk across the parking lot and get locked after dark half the time anyway.
I am trying to figure out if one standard porta potty is enough or if we should order two, and whether we need a separate handwash station since kids will be eating. The lawn is flat grass and a truck can pull in from the curb. We also have a few neighbors who use wheelchairs, so I am wondering if we should make one of the units an ADA unit even though this is a private HOA event.
Anyone run a short evening outdoor movie or similar neighborhood event? What actually worked for count, unit type, and where you put them so they were not right next to the screen?
