@Linda3345 "Because we do live there, I also feel I need to tell the guests when we are Not going to be on the premises when they are, which also happens. "
I would be a bit circumspect with that. You have an advantage as on-site hosts in that guests will not be able to sneak in extra people or throw a party. You don't want to negate that.
Obviously if you are going to be out of town when guests check in, you would probably want to let them know that, but I wouldn't mention it until the day before check-in, and I wouldn't be forthcoming about how long you'll be gone. For instance, if you are going to be away for a few days, it's enough to say, "We're going to go visit our son and his family tomorrow morning. We may come back in the evening, or we might stay a few days, we're just going to play it by ear. Of course if you need to reach us, we have our phones at hand".
What you want to avoid is the guests thinking, "Oh cool, they'll be gone for 3 days, lets invite Joe and the gang over." Let them think you could drive back in at any time. If you have a quiet older couple there, who you feel confident wouldn't do anything like that, of course use your judgement, and you might want to let them know exactly when you plan to be back.
