Venues

Addresses kept once and attached to every event held there, with a map and directions on the page.

In the free plugin Read the manual

A venue is an address, a phone number and a name, kept once.

Attach it to an event and the details appear on the event page and in every message about it. Change the phone number and it changes everywhere, rather than in the nine events that quoted it.

Events held in the same place group together, which is what makes a second event in a venue you already have a choice from a list rather than more typing.
