Hello @Othniel3
Ideally you could list under three different listings!
- Parent listing = here guests could book both bedrooms (family or friends)
- Child 1 listing = 1/2 person booking one of the bedrooms
- Child 2 listing = 1/2 person booking other bedroom
You would have to link the Parent listing calendar with the other two so that if you get a booking for both bedrooms, then the other calendars for child 1 and child 2 will get automatically blocked and will show unavailable.
You'll need to make it clear that there will be shared spaces in the home and provide locks on doors but I'm sure you've got that covered already
Info on how to synch calendars below:
