So, I just called up support as this feature (showing a discount for any night selected as opposed to last minute or longer stay discounts) is being rolled out slowly to specific regions as best as I could tell. This is really (IMHO) stupid, as the people that want it now should be able to simply request it. If airbnb is worried about how important it is, let us decide as this haphazard mechanism makes no sense. There are people that will never use it. So it should just be a simple check box that we as hosts decide if we want and therefore allow us the opportunity to show it when needed, not on airbnb's schedule. For instance, I don't need it inthe summer, i need it now.
