[support] Views filter rooms by occupacy

[Jamie Holly]

How are you associating the rooms content type to the reservations one? 
If you're using entity reference, then you would want to create a 
relationship with the reservations content type through that reference 
field. Make sure you don't check "require this relationship" then add a 
filter so that the related node (reservations) nid is NULL.

The other option is in a custom module, using hook_views_query_alter. 
Load the reserved room nids, through a normal DB query, then add a NOT 
IN condition to the list of nids. Here's the documentation on that hook:
