I have a few families - mostly moms on mat leave or friends of theirs that will use a day if I have it. If I am down in kids or someone is on vacation and I have an opening that day then sometimes one of them will come and use that day to get things like a haircut or shampoo carpets - things not easily done with kids to tend to. Works great for all of us. Drop is done on a first book first get basis and is subject to regulars not needing the space that day. Payment when I do it is at pickup. I charge $40 so it is easy to stop by an ATM and get the cash. The biggest thing is that should the original child change their mind the drop in can't come due to numbers. Good thing is I am getting paid twice for the same spot.
