I think I might have a fundamental misunderstanding of how taxonomy works in Drupal.
I've set up some vocabularies, such as 'accommodation', 'things to do' and 'eating out'. Within those, I've added parent terms 'accommodation types' and 'ratings' for accommodation, 'nationality' and 'suitable for' for eating out and so on.
Both vocabularies share some common features, though, such as 'location'. I set up 'location' within the 'accommodation' vocabulary first and then tried to make it available to 'eating out' by setting it as a parent, but I could only see other terms within the vocabulary.
What is the best way for me to allow each vocabulary to share a location without manually recreating and updating a 'location' term in each vocabulary (which surely must be the incorrect way of doing what I'm trying to achieve?)?
