During your messaging you can remind the guest of your house rules and Airbnb protocol and tell them they can cancel within 48 hours for a full refund from Airbnb if they cannot abide by both. One of the most important protocols is that the booking individual be present. They are the responsible person if anything goes wrong. If they give you a story about how they will arrive later, not at booking, tell them your insurance requires the person booking to be present at all times. In your house rules state that you want a list of names of additional guests, who will be required to show ID.
Are you present when they arrive? If so you can deny entry if the person booking is not present, if you are not there to hand over a key you are pretty much not in control and and are open to more trouble. Hosts who seem to have these problems usually allow groups and many are not on the property or even nearby. Short minimum stays, instant booking, and last minute booking also seem to go hand in hand with problems from what I read in the community center.
I have had 3 such bookings and on each one, when I learned the booker was booking for a second party I required that person to send me a copy of their photo ID and be given access to my email, so I could make sure they agreed to house rules and could communicate with them. The better communication you receive from a guest the better. Good luck.
