"... doing the Hokie Pokie in a circle limits how far you can grow. As the circle kept expanding, it became less and less space efficient. People were excluded simply because there wasn't space for them to join." Keep the original small circle, and form progressively larger concentric circles around that. Or turn in into a line dance with lots of rows.
