I'm tempted to suggest that you start college first, adjust to the whole college experience, and then go do the CP. Going off to college was a big change for me, and I don't think I would have been able to handle living in my own place straight out of high school, like you would have to for the CareerStart. Of course, that's just me. I know everyone's different.
And from personal experience, don't worry about a major! Use your first year in college to take classes in whatever you're interested in and feel it out. I took forensic anthropology, an acting class, Victorian literature, Czech language & culture... it was AWESOME. I loved all my classes and realized I was a Liberal Arts & Sciences kind of girl. I'm looking into Disney careers for myself now, and it seems that there is a place for everyone, no matter what your major or interests. So I wouldn't try to tailor your major to Disney - find a major that you're interested, and then find your place at Disney with it.
