Outdoor November wedding: handwash stations freeze?
We're getting married at a farm outside of town in late November, ceremony at 4 PM and reception until 11. It's 90 guests, a catered dinner, and an open bar. I've rented three standard portable toilets and one ADA-compliant unit for the cluster, plus two handwash stations. The forecast says it'll drop into the 30s after sunset. I'm worried the water in the handwash stations will freeze and be unusable by the end of the night. They're on level grass, and the rental truck can pull right up to them for setup. Has anyone dealt with this? What do rental companies do to prevent freezing, or should I skip them and just use hand sanitizer dispensers?
