If I may, I suggest you add to your House Rules:
"In order to book a reservation at this property the Primary Guest's face must appear in your profile photo, for security reasons." and "Registered Guests Only= No daytime visitors or overnight guests."
Always message the guest via Airbnb (so that you have proof of every conversation).
If they don't reply within an hour, text their cell but only say "Hello XXX, This is your Host XXX. Please go to your Airbnb account and reply to my Airbnb message. Thank you."
In your Airbnb message to the guest:
Ask the guest to please update their profile photo to a photo of him/herself without glasses, hat, etc. for security reasons.
Then ask them to confirm the exact number of adults/children/infants and vehicles who will be on your property.
Always a good idea to have these discussions so everyone is on the same page.
I agree with your initial point, I fear someone will book the min. number of nights over the 4th of July weekend. I've noticed many hosts are changing their 2 night minimum to 3, 4, 5, 6 or 7 nights.
I think this summer is going to be a very busy summer!
