I need opinions!!

I am in high school band. There are five girls in my section(I play oboe) I was thinking about having a sleepover, so that we can get to know each other. Last year some of the girls got in a fight, and there was a lot of drama. I just really want our section to be close this year. But at the same time I feel like it might be really lame and stupid. So should I have the sleepover? Also what are some things we could do at the sleepover, because we really don't know each other that well.
