Lol, @Mark26, they could block a long period or your minimum stay, hope that it is wedged in by other bookings, cancel and watch your calendar to know, if your house is empty.
But the main concern may not even be well prepared burglars, it’s rather people , who might be annoyed in the following conversation, then they cancel and then they might be staying close and have time to walk over and do some harm. Sometimes guests get ideas, what might be included and be annoyed if it is not. If the stay is cancelled for such a concern, it’s reassuring if they cannot walk over and lay in wait for you.
I had a guest, who wanted to upgrade the offering from shared room (kitchen) to shared bed. I would have liked to have a Wipe button, to remove all codes, address and phone numbers from his account, phone and brain. 😉
Some get their interesting notions immediately after booking, so witholding the last details served me well a few times.
