We love hosting on Airbnb; however, we can't understand why you're pushing the instant book feature. We had it on for a short time, and someone booked a reservation about three months out. Because we didn't know our schedule that far out, we hadn't blocked the dates and subsequently had to cancel on him, thus costing us superhost status for a year. We refuse to use instant book for this reason, but are being punished by not having our listing as well promoted. It's a no-win situation. Looking through the discussion threads, it would seem that no one likes that those who use it are privileged.
