When bookings are received from channels they might on rare occasions be divided into different rooms. If the same room is available for the whole period, the booking will of course be put into that particular room. However, if no room is available for the whole period, the booking will still go through.
Why does this happen?
The booking channels count the room availability per day, not for specific rooms. For example, let’s say room 101 is available on Friday and room 102 is available on Saturday. The booking channel will interpret this as: “Friday: 1 room, Saturday: 1 room”, or in other words: “1 room is available from Friday to Saturday”. Technically, that is true, but it creates a problem since no guest wants to change rooms during their stay.
Is there a solution?
Unfortunately, this is nothing that can be automatically prevented or solved. However, in most cases, you might be able to move around bookings to make room for an uninterrupted stay. You will probably find the drag-and-drop feature in the calendar overview useful for this purpose.
It may also help to regularly review the Calendar page and try to optimize the room assignments. By reducing the number of small gaps and creating bigger chunks of availability, it is more likely that new bookings can be added without issues.
