You can assign one or multiple room types to a room in FrontDesk Master.
It means that your ROOM 1 can be sold with multiple configurations, for example, as Triple Room and Double Room at the same time or 6 Bed Dorm and 6 Bed Female Dorm. If rooms are sold under multiple room types, first booking determines which room type should be in use per specific date based on the received bookings.
In order to assign the room types to the room, go to Property Management / Room Manager and open a room window. Click on Add Room Type button:
Then, select the room type you want to add and click on Ok button to accept the choice.
Remember to Save the changes.
The room will be visible on Bed View with two room types assigned:
