If they are breaking a house rule, then you have the right to ask them to leave - but if you ask them to leave, contact CS first.
You can have CS cancel a reservation on your behalf and this DOES NOT go against you in anyway.
I had a guest break a house rule (smoking inside) and they would not stop. CS contacted the guest and first tried to resolve the issue, however the guest did not want to follow the rules, so he was told by CS the stay was being cancelled and he was asked to leave the property. ABB cancelled the reservation for me (and it went against the guest for not following rules - not me).
This would be the same case.
If she does not want to follow the rules with the amount of guests you allow you can first try talking to her about it and let her know you are very firm on how many people are allowed. If she does not listen, you can let CS know that she is breaking a house rule and if she has more than 5 guests let them know you are *uncomfortable* with these people staying in your accommodation. Key word *uncomfortable* CS likes to hear that word.
Good luck! 🙂
