Moving out and late stay

Hi. I completely forgot to fill out the late stay form and it's now closed I believe. Is there any way my college will grant me the ability to stay 4 or 5 hours past the move out date? I will call them tomorrow and ask, but I'm pretty stressed right now. What happens after 3 pm on Saturday, do they check if I'm still in my room (I can only move out on Saturday in the evening), do they charge me? Is there anything I can do?
