@Rick4446 A traditional B&B as you describe it is actually a charming but rare thing to find on Airbnb. Your home looks like a really cozy place to hang out and the food looks delicious. I can't blame people for wanting to linger around and enjoy the vibes.
Under the current norms of short-term rentals, guests have access to the rented space for the entire period from check-in to check-out, and they make their own decisions about when (and whether) they'll go out and do stuff. I would find it pretty invasive for a host to insist that I leave the property altogether at certain hours of the day.
However, it's completely fine and normal to set access hours for the communal areas of the house. You might say, for example, that the dining room is closed between breakfast and dinner and that the outdoor spaces are closed at 10 PM. But I wouldn't recommend denying anyone access to their bedroom or bathroom at any point in the day. If you're unable to leave the house when a guest happens to be in their own room, it sounds like something else (e.g. locks) has to change.
