She is able to attend as long as she has a guardian with her. Anyone under 21 without a guardian i believe has to leave by 9:00 or 10:00. I'm going to probably get there around 7:30 to get our tables and such, and to have a bite to eat before the party. If you happen to get there early i should be there. Most people probably won't be showing up until around 8:00 - 8:30.
