After the 2 hour minimum, at what point are you charged for the third hour? For example, if I drop my kids off at 5:00 and pick them up at 7:01, do I have to pay for 3 hours? Or would it be at 7:30 or even 7:59? I have six kids so the difference between 2 or 3 hours will be $70, but I would love that extra hour for date night with my husband! Just wondering what to plan for. Thanks in advance!!
