I have also heard wonderful things about her costars -- Daniel Letterle, Vince Rimoldi (I think I know your sister -- Cinderella), Dequina Morre, and the actor, whose name escapes me, who plays the gay teen.
Robin De Jesus plays the gay teen. I am very biased because he is one of my sister's best friends and he is so nice. I always see him. He really shines in CAMP also.
