It's my understanding that if you put your yellow tags on the bags, they won't even be delivered to baggage claim if you land before 10. So it might be out of your hands at this point. (I'm sure someone will correct me if I'm wrong!)
If you land before 10 and don't want to get a knock on the door at 2 a.m. (or whenever) with your bags, you can ask the front desk to hold them until morning when you check in.
Hope you get there soon!!
