Couple of suggestions. If any one from your daughter's high school or church is currently attending Auburn, then she could contact them via Facebook and arrange to meet them for about 1/2 hour while on campus. My daughter & her friend did that while visiting Auburn during War Eagle Days. The one-on-one student perspective is priceless.
In addition, I would recommend meeting someone from Honors College (if she currently qualifies) or someone from the school which she plans to major.
Since Auburn is a college town, go to Toomers Corner, get some refreshing lemonade, and then walk down College Street just north of Toomers Corner. There are small places to eat which students like to frequent.
Also, what are your daughter's interests? Arrange to meet some students who are part of organizations with similar interests. Auburn has over 300 organizations

Also, Friday is the day before Auburn/Georgia game in Athens, Georgia. There may be some student events held in Auburn that day in preparation for the game.
