Most STR ordinances exempt children under a certain age (commonly 2 or 3) from the occupant count. Confirm your specific permit conditions with Planning.

No. Overnight occupancy is capped at the number set on your STR permit regardless of sleeping arrangements, and exceeding it is a permit violation.
Does the occupancy limit apply to daytime visitors?
The primary limit is overnight, but RCMC 8.34 also discourages daytime gatherings that turn the unit into an event space. Check your permit conditions.
