DadTwoGirls,
I agree with everything you wrote and, sure enough, I would rather have her in a smaller university. This option would, as you wrote, minimize the implications of any limited mobility, but again, there are budget constraints. Case Western Reserve University, with 5.200 students, and Emory, with 7.000 students, both seems to be a god fit if she gets merit aid.
Thank you for your inputs.
