Maybe leave a line for "Special Dances / Activities" so it becomes a simple conversation .. otherwise you might get some who want it but "forget" about until the day before. No need for separate lines, but one "other" heap (throws, shoe game, dollar dance, etc, etc) might still make sense.
I still have all of those events on my sheets.
I have periods of time where everybody does events,
and others where they don't want to do anything.
But I only list the basic, traditional things on my info sheets.
I also have a section about "Special Events"...
which can be filled out for speeches, shoe game, apron dance, etc.
