Tracking activities over the summer?

Our school is new to Blackbaud this year. We operate multiple summer camps in June and July, and we are trying to determine if we can set them up as activity groups in BB for attendance and communication purposes. Our school year is configured to end June 30 and the new year starts July 1, so some camps would span multiple years. Is anyone using BB for this purpose? If so, how have you configured those activities to function best?
