@Katrina79 has some excellent points.
You could ask that all of them meet with you for checkin and hand a printed copy of your house rules to the adult who will be staying.
If you stress that the party who booked will be held entirely responsible for any damages perhaps the guests will be extra careful.
That would include damages caused by a malicious review.
I’m not sure what would happen if you need to invoke the Host Guarantee, but it’s not worth much anyway so I probably wouldn’t worry about it.
Your big challenge will be in assessing the family dynamic.
Decent people won’t do things to injure a family member.
Then there are the others…with irresponsible, drug addicted, or insane offspring.
