Is there a cancellation policy in the original contract? Is her vacation 2 weeks or 1 week? She can't really withhold paperwork or receipts if you choose to withdraw and go to another daycare. You may want to look and see if you can find alternate care before you say anything to her that way if you can't find someone else you haven't burned a bridge. I would say that you should give her at least 2 weeks notice if you do decide to go with someone else. Good luck.
