Does this sound like a good idea?

Okay, so I've always had a dream of living in Hawaii. I'm in my junior year of high school now, and I'm looking at colleges. I have a friend that moved to Lihue a few years ago, and the way she talks about Kauai, it's everything I'm looking for. I want to study marine biology, and what better place to do that than Hawaii? I'm strongly considering going to Kauai Community College, it's only two years, but it will give me plenty of time to find out if that field and living location are what I want. I know that the living costs are crazy expensive, but I'm starting to save money now and am learning how to live on a tighter budget and I'm applying for scholarships to help with college. I'd be 19 going on 20 by the time I move there. So, does that sound like a good idea? Tips for Hawaii living and saving money would be great too.
