@Brian1963 "Please note there is a max of 6 adults at the cabin. We allow for 8 only when children are present, and families need the extra sleeping space."
What this actually says is that you will accept 8 adults and an unspecified number of children as long as there are 8 adults.
I’m pretty sure you don’t want that.
You can set your maximum capacity at 6 adults, with no more than 8 guests total including children.
Personally I wouldn’t allow more than 4 adults and 4 children, which is going to be bad enough.
I would expect some huge messes, lots of damage, and bad reviews if you object to the destruction.
We don’t accept children anymore because of this, and our insurance wouldn’t cover them if we did.
