I don't give any free vacation time! Why should you have to lose out on your income because they decide to take a vacation! Personally, I would make them pay full fees. If they were with an agency they would have to pay...the same at a centre. I have a family who wants to take the whole summer off (she is a teacher), but they have agreed to pay for the entire summer to hold the spots as I could almost surely fill them...I just can't afford to lose out on all that income, much as I understand the parents' desire to save money.
