I take 3 weeks unpaid and if the family takes holidays a different time from me, they still pay full fees. I have 1 exception for this and it is for extended holidays of an absence longer than 3 weeks...basically for teachers. They pay half fees over the summer to keep their spot for September. With the half fees I allow them to bring the child a certain # of days/month. I give them a list of available days and they choose from there.
