Advice needed! We are having an outside wedding this June at a friends house on a lake. We are expecting anywhere from 120-140 people. How many portable toilets do you think we will need. We are on a budget, so trying to decide between:
1. Flushable unit with handwash, will have to put lighting in it, approximately standard size $175 (could get 2)
2. Flushable unit, handwash, full length mirror, lighting, larger size (can walk around in) $250 (get 1)
Thanks!
