Summary is…say your whole house is the “Kingdom”, and 2 individual rooms are “Chalets”. Then:
Link your top-level “Kingdom” as follows:
- Link the Kingdom to Chalet One
- Link the Kingdom to Chalet Two
- DO NOT link Chalet One to Chalet Two
Now:
-If someone books the Kingdom for certain dates, then Chalet One and Chalet Two will be unavailable for those dates
-If someone books only Chalet One for certain dates, then the Kingdom will be unavailable for those dates, but Chalet Two will still be available
-If someone books only Chalet Two for certain dates, then the Kingdom will be unavailable for those dates, but Chalet One will still be available
