As a high school team, we were not allowed to miss any practices unless it is an emergency or like "you can't get out of bed" sick.
We learned our choreography usually in May near the end of school then practiced all summer. Since we were were considered a sport at our school, we had to follow state regulations which gave a 2 week break from organized practices. So that gave us plenty of time to have a nice vacation. Then we would get a break after camp, where we competed, and then we would start back up learning stuff for games.
I honestly can't stand when people aren't at practice. We don't really have a problem with it, but my other base got really sick last year and I didn't do anything for about two weeks. And when I did I was stunting with a sick girl! Haha
