Some users rent out House and its rooms and they need to disable reservation of House if at least 1 room is booked and vice versa - block all rooms if the house is booked. Or if it is the hostel you might need to rent out the whole room or each bed separately.
So there is no special functionality to link the whole house (room) with its rooms (beds) in the plugin, however there is some kind of workaround:
You may add 1 accommodation type for House and 2 (and more) accommodation types for rooms (or single accommodation type with 2 accommodations if there is no difference between the rooms).
Then navigate to Bookings > Sync Calendars and here you may put ical link of the House to the calendars of each Room, so that the Rooms will be able to import bookings from the House and will be disabled for reservation. And then copy ical links of each Room and paste them to House calendar, so that the House could import bookings from each Room and it will be disabled for certain dates if at least 1 Room is Booked. Here we recommend adding some unique ending to each accommodation ical link to modify them as different booking providers e.g. add &a=1 and &a=2 to ical links. For example, normal ical links of accommodations are
Accommodation 1 -
Accommodation 2 -
You should paste them to the calendar of the House in the following way:
Accommodation 1 - http://localhost/?feed=mphb.ics&accommodation_id=100&a=1
Accommodation 2 - http://localhost/?feed=mphb.ics&accommodation_id=105&a=2
You may add anything you want after & symbol as I used a=1 as an example. The main thing is that they should be different.
Note: it is recommended to keep the option Export admin blocks. disabled via Accommodation > Settings during such scenario.
