They're not essential attributes of a booking (or engagement, or performance). I toured the US as a sound engineer. We didn't have a Northern leg or a New York leg. That's one clue.

That every set of users might have a different way of talking about groups of performances is another clue.

You'd likely profit from separating the essential attributes of a booking from the admittedly arbitrary way people will talk about groups of bookings.
