Have you visited all of the schools too? I'm sort of specifically thinking of the dorms because being on a campus with a miserable dorm is not fun.....(of course - life is what you make of it too).
Also - I don't know how close you are to your family and how much you hope to come home for holidays, etc. Our family is very tight knit and our son's first major holiday away from home (Thanksgiving) was really rough. But Art had just retired from the Air Force and we were settling in w/ jobs and stuff and we couldn't afford to fly him home till Christmas....that first year was pretty rough on him. Then again - we'd homeschooled for 12 years and he has a twin sister that he was used to talking to about everything....
I'm dying to find out where you eventually decide to go...
