Bethesda Summer Music Festival Opera Program

Has anyone ever heard about/attended this program? My voice teacher at GMU mentioned it to me and it is open to grades 9-12 as well as college and young professionals. I am a junior in high school and am looking for a good summer program or two that would help me grow as an artist and look good on my resume. The program is doing Carousal and Le Nozze de Figaro, two works that I love! Anyway does anyone know about the chances of me getting in, is it worth it? Would getting two roles out of this program help me in the long run?
Thanks!
