....As for the issue of "paying for daycare on days they are closed"... I suspect that you pay a flat fee (monthly/weekly)? At the beginning of each year (or the end of the prior year, as the case may be), the daycare will sit down with a calendar and determine what days it will be open and what days it will be closed (just as any other business does-- and that includes law firms). They then figure out the operating expenses and costs associated with the days they will be open, and allowing for reasonable profit (as daycares are generally not non-profit associations), they arrive at a dollar amount for tuition. Your tuition is then prorated over a 12 month/52 week period, and the days that the center is closed are already accounted for in that amount. So it isn't that you are paying for days they are closed-- you aren't paying for those days at all, as they have already been "deducted" from the overall tuition.
And yes, I have kids in daycare, the daycare is closed 2 days over Thanksgiving and 3 days over Christmas, and yes, the full amount of tuition is due for both November and December.
P.S. And I'm a lawyer and my office is, in fact, closed the day after Thanksgiving. Yes, it is a paid holiday for all of our staff.
