We had a similar need in that a client with several “store” locations across the country needs to associate their “stores” with events that take place both at their “store” location and at other local “off-site” venues (golf courses, parks, etc.). The challenge was to be able to associate each “store” location with both “store” and “off-site” locations, while clearly separating out the “off-site” events in terms of displaying an address and map for the public to find where the actual event was taking place.
We ended up creating a custom plugin to add a new category taxonomy to each Event, and added our “store” locations to both that taxonomy and the regular “Locations” (which list both “store” and “off-site” locations). It’s duplicating data-entry, but it allowed us the flexibility to filter events by “Location” (actually, our custom taxonomy).
Now we’re just trying to clear up a bug related to our custom taxonomy not saving properly to recurring events (saves to regular events just fine), and added to another plugin to create a nice month/agenda view of the calendar and some custom styles for the Locations and event listings views, it’s becoming quite a nice events calendar.
