Family reunion weekend: one unit enough for about 60 people with outdoor food?
We're hosting a family reunion at my parents' place next month, Saturday and Sunday afternoon. Roughly 60 people total, not all at once, with a potluck under a tent in the backyard. The house bathroom stays for older relatives who need it, so everyone else would use a standard portable toilet out by the garage where the truck can reach.
I'm stuck on whether one unit covers two days of that crowd with food out all afternoon, or if we should get a second one. Some cousins want a handwash station next to the food table. Is that overkill for a private yard, or worth it when people are handling serving spoons all day?
No alcohol planned. Ground is level grass. Looking for what you'd order in the same spot.
