In this article, I will explain what is the difference between Inquired, Optional, and Confirmed reservations.
Confirmed - This status means that the reservation is confirmed by all parties. The guest will be surely arriving on given dates, from confirmed it can only get to canceled status.
Optional - means that the reservation is not yet confirmed or canceled by the guest or employee. But the room is already taken out of availability.
Inquired - this status of the reservation is similar to optional, it can be canceled or confirmed by the guest or employee. But the reservation is not being assigned to a room, therefore doesn't affect availability.
