sounds good to me! i have never charged for summer for teachers due to the fact that I always manage to pick up a school aged kiddo to take the teachers childs place, if I couldn't fill the spot though I would require some type of payment through summer as well. You may want to have the teacher place a holding fee for when they return in the fall, if you don't already....i have had a teacher not return their child to my care the following school year and inform me too late to fill the spot before I lost income. Not cool! other than that sounds pretty good.
