@Deborah1156 Oh, I didn't think you were brushing off Andrew's comment. Your responses show that you are quite open to other's ideas.
I just know from all the posts I've read over the years that hosts are constantly having to refine and amend their listing info, because what we think is common sense, or clear, or can't imagine a guest would be so disrespectful as to do, is often not clear to guests. And if things are left open to interpretation, or hosts bend their rules a bit to try to accommodate a guest, they'll often take advantage.
Like asking if they could have a couple of friends over for dinner, the host says okay, the "couple" of friends turns out to be 6, and the neighbors call complaining because they're all drunk and loud at 1am.
Nothing wrong with taking things on a case by case basis, you just have to be cautious. If a 65 year old couple wants to have another retired couple over for a game of cards, or their 10 year old niece over for the afternoon, that might be totally an okay thing to approve.
