When you say you put the password into the House Rules, by “password” do you mean the access code to the house? Isn’t it a security issue since the rules are visible even before they book?
Or is it just an arbitrary code they need to recite to you when they book? If so, this seems kind of kindergarten-y, I could see how some guests could be annoyed by this.
On the other hand, putting something the guests NEED inside the House Rules section could be a genius solution. I’m just thinking what could that be, so it’s not a security issue. My first thought was Wi-Fi password, but that opens up a door for unauthorized access.
Maybe it could be a part of the WiFi password, like a suffix or a prefix and the rest would be available as private info.
