Do Last Minute searches work with Unavailable dates?

No. Homes that do not use the new explicit availability will not appear in Last Minute searches. The reason is that entry of Available dates is active whereas availability due to the lack of Unavailable dates is passive. If a home only uses Unavailable dates, we can't know whether a particular period is really available or whether it's just because a calendar is not actively maintained. The use of Available dates and therefore Last Minute searches favours members who keep their calendars up-to-date.
