@Bhumika Just as @Mike-And-Jane0 stated, my properties sleep 2 times the number of bedrooms offered. My AirBnB 2 bedroom cabin will accommodate 4 human beings of any age or size. My larger 3 bedroom properties are advertised as sleeps 6, even when a sleeper sofa or other alternate bed is available.
Our properties have licensing or are zoned for a certain number of persons. In NC, persons means a living, breathing human being of any age or size, so infants and children COUNT. Some AirBnB guests think that all children are free. Our larger properties are especially prone to guest numbers in excess of the advertised capacity, as children "can sleep on the floor". We are not interested in overcapacity and potentially destructive guests. We do not advertise sleeper sofas, futons, trundle beds, air mattresses or any alternate sleeping space.
I have had guests who neglect to mention children or who have invited other adult persons to stay a night here and there during their reservation. I deal with these situations on a case-by-case basis, but the booking guest is usually informed that they must seek a different accommodation for themselves or their extra guests. If told that my licensing is in danger of revocation, they are usually compliant.
