Need of Help

I have an issue- I need some help! I am having surgery tomorrow and it was scheduled for the late afternoon because I have the summer co-op older girls here for my day. I have pioneer inspired crafts all ready, making butter and biscuits, dolls, and candles, it was my plan to finish the co-op and check in for surgery later. Unfortunately, I got my time slot bumped and I am now the first patient and have to be there at 11:00. Well summer co-op starts and 11:00 and ends at 3:00. I called Bethany to see if I could switch with her for next week but her kids arent on the list and I believe she is out of town. My question is this... I would have someone come here to do it but I will be out of surgery and maybe home before co-op is even over and not wanting people here when I need the rest and so it leaves it to I may have to cancel it for the older girls or someone host it and I will switch your age group next week? Or anyone have any other ideas?
