It’s doubtful that you will be able to cancel without a penalty.
You might be able to get the guest to cancel voluntarily if you let them know that:
1. They cannot have 10-15 people staying there or visiting
2. Public urination is unacceptable
3. Littering is a misdemeanor and will be reported
4. Their early arrival constitutes trespassing
5. If they violate any other rules or local ordinances they will be required to leave immediately
I would give them notice in writing via the Airbnb message system. Keep it short, concise and factual.
Good luck. . .
