I'm astonished there's no clear answer to this question! I've got 5 inquiries sitting in my dashboard for inauguration weekend - which someone has already instant booked (and not at the highest possible price, by the way! That's my next question.)
Do I decline them or just let them sit there? I've sent messages to a couple of them, but it's unclear what the protocol is. By now they should be able to see that those dates are booked (- or perhaps Airbnb sends them an alert?)
