Grace Conrad is a main character and protagonist in Unaccompanied Minors. She is a snide, snobbish, conceited, nerdy, and arrogant rich girl who regularly visits Hoover International Airport around Christmas. She used to be a dork, as discovered by Spencer Davenport, who develops feelings for her. Like Donna, Grace's personality changes over the course of the movie. In the end, Grace reveals that her parents, sort of, disowned her, because they don't really like to spend time with her, and she spends her Christmas with Spencer and his family after he invites her to.
She is played by Gia Mantegna.
