I recommend looking at the Oxford Campus of Emory. It is a smaller campus that is easier to get into that the student would attend for two years and then they would transfer to the regular Emory campus and the degree is from Emory. I've known people who have attended it and really loved it.

While not necessarily having a big college feel, you could also check out St. Mary's College of Maryland - as a public small college it has a bit of a different feel than a lot of the privates.

Simmons College is an all-girls school in Boston that may be worth looking into. Given all of the colleges in Boston, it definitely allows for a "bigger" feel.

Pitzer College is part of the Claremont Colleges in California. It is a small school but is directly adjacent to the other Clarement Colleges for a "bigger" feel perhaps. It definitely has a liberal vibe though. For example, they recently instituted a major in "secularism." Students there can take classes at the other colleges as well.
