<p>What about Idyllwild?
I went for the first time last summer for the symphony orchestra program, but I’m not sure how it is for voice. It’s about 2 hours away from Palm Springs in California. It is a boarding arts school similar to Interlochen just closer to civilization and no uniforms. The food is actually pretty good and you are in dorm rooms with bathrooms in them. It’s a TON of fun and you meat a lot of outstanding musicians from all over the world. I think the programs all vary in length and a lot of people stay for more than one session.</p>
