What happens when these families bring their children and then can't get back to pick them up because the weather has gotten so awful or their car breaks down in the cold weather?
Charge a penalty rate or you chose to close early. They won't come on their own, you must make the decision.
Their contracted hours are until my close time
Change your contract to sliding hours if you don't want to work until close. Many here do it successfully.
I do allow my families vacation days (pro rated depending on their schedule) each year as well, but nobody ever takes advantage of them.
I offered it free for my first 20 years. They stopped taking them about 8 years ago. I took it out of my contract 4 years ago. Nobody noticed.
