hello @Michelle1818
First, let me say, your listing is beautiful!
For me, if I had a 3 bedroom house, that sleeps 8, and it was booked for only 2 people, alarm bells would ring. Why such a big place for a small group?
I would ask the question, and tell them that for insurance purposes, only the people listed in the booking would be covered for insurance. I also would put on the listing that you live 2. min away from the property.
I checked your listing and could not find the mention of the ring camera. Maybe add it next to the listing of "Wifi, Roku, 3D tv and movie assortment, board games for a break from the sun".
I would add this as many times as possible, saying that is for their security as well.
