Get thee to campus.
I am in a non-traditional field for MBAs, and plan to stay that way. A well-regarded school is great, and like you, I hope to have several options which will range through the elite and trans-elite. You can only second-guess your career options and plans so far. But what about the experience of business school? I knew I wanted an advanced degree, and an mba made the most sense. But part of getting an advanced degree was enjoying the experience of it, of being back in school, of learning, and expanding my horizons. This stuff is impossible to quantify, but an important part of it is fit with the student body, teaching style, social opportunities, electives, etc.
I am just so touchy-feely it makes me sick, but that's what it will come down to for me.
