Airbnb guest problem: unauthorized guests and possibly a party

[Mary Pastoral]

New to hosting and currently hosting our first problem guest. 

A guest with no reviews asked to book our place for two guests since she will be spending time with her sister for her sister's birthday. I asked if she read the no party policy.  She said that it is no problem since there will be no party. 

We have security cameras in the outside of the property. Since 6 pm last night up to 4 am multiple guests came and went and there are 6 cars in the driveway up to this morning. Property has no smoking policy, and they were seen smoking at the porch and I am not sure if they are smoking inside as well. There's a quiet time of 10 pm to 6 am written on our listing, which was not followed as well. 

The guest checks-out tomorrow. What do you do in this situation?

1. Wait until check-out and just call the guest's attention if there is severe damages on the inside?

2. Call their attention today and say that we will not charge extra guest fees as long as they clean up? (I am not sure of this since they clearly do not care about rules. They were smoking weed while looking at the security camera. ) 

Also, will Airbnb penalize host if we just accept guests with prior reviews from now on? Thank you.
