Party Animal or Glutton for Punishment?

I recently hosted a slumber party for my oldest daughter who just turned twelve. We had five girls plus my two. If you think this sounds crazy. My ten year old daughter usually invites twelve girls. The five was like a walk in the park. I fed them, we played a couple games, decorated locker mirrors, and I introduced them to the wonders of the DVR. All in all I think a good time was had by all. I enjoy throwing parties. Mind you I stress about the house, what we will do, and if I will embarrass my children enough to keep them on their toes yet not scar them for life. I never had a slumber party as a child, so I want to make sure my children don't miss out on any fun.
