What type of role do you think I would be most likely to get?

I am looking into a summer theatre camp that is doing Footloose. The age range is 10-16 (I'm 14). I would want to be Ariel or Rusty, but would also be happy playing Wendy Jo or Urleen. However, somehow I have a feeling that I would end up playing Vi or Ethel because of my height (I'm 5'8") and the fact that I am often mistaken for older (when I was Grace in Annie at school, many people thought I was a teacher) despite the fact that I maybe look 15 or 16. Do you think I would be more likely to be cast in a teenage role or in an adult role?
