Newsletter
The first mention gives the date, the time, the room and whether tickets or sign-ups are needed. The second mention opens the sign-up, names the capacity and says when a second performance would be added. The last call states how many seats remain, or that it is full and where the overflow is.
Social
Save the date is the date, the time and the sign-up link. The reminder post the Friday before is for ticket holders: doors open at, seating is unreserved, where to park. The day-of post is a photograph of the room before doors open, with the start time.
Sunday Announcements
Announce it two Sundays before with the sign-up open. The final announcement is the Sunday before the Saturday, with the seat count and the arrival time.
Website
The page holds the sign-up, the time, the length, the room, and the arrival instructions: doors, seating, parking, and whether the program is suitable for toddlers. Published four weeks out so the first newsletter mention can link it.
Print
A poster in the children's wing and at the entrances, with the date, the time and the sign-up address. Due a week before it goes up.
