First thing, love your story! I am doing the same thing with grad school.
Okay, so first I want tell you about what got me to attend my undergrad #1. I went to the collge of saint benedict/s ain't johns univeristy in mn. I am from ohio, so its a bit far. But I loved everything I read and applied. They offer a program for out of state students to come visit for the weekend. All I had to pay was half of my plane ticket. Stayed on campus and learned about the school. They got us between the airport and school, food, everything! It is really well known and big on study abroad, two things that drew me in.
While CSB has alot of similar things, I recommend seeing if Stanfordd has a program like that. Or any out of state school she wants to see. Link for csb program below:
