No... I work in a childcare center, and having sex anywhere in the building just seems so... wrong!
That said, the center is more of a house type building, with a nice fold out couch in one of the rooms. One time when my partner was visiting, and work was closed for a week due to the owner going on vacation, my boss did say that my partner and I could stay at the center. It just didn't seem right to me, so we chose a hotel instead.
