All your schools are good academically. Check to see which, other than Eastman, have a performance component to their program. And check to see which have guitar faculty or are located in an area where a good guitar teacher is available. You can find all of this out by looking thoroughly at websites, with the possible addition of a phone call or e-mail to the music deparetment about guitar teachers. (When my daughter did this one LAC offered to find her one!)
For instance, a few minutes on the Harvard website, which state that it does not have a performance program, nevertheless reveals that it does have some performance-based classes and will give credit for private study outside the university through independent study. Also, “Undergraduates receive Harvard College credit for participating in the Harvard-Radcliffe Orchestra, the HR Collegium Musicum, the Harvard Glee Club, the Radcliffe Choral Society, and the Harvard Dance Project.” It also offers a double degree program with NEC that you can apply for next year if you so choose. Finally, check the teachers available in the Boston/Cambridge area (Ellliot Fisk is at NEC, or was last time I looked.). Google them, meet with them, whatever helps.
You can do this for each of your schools. It doesn’t take that long. Classical guitar can be a little harder to ascertain than some other instruments. There are great teachers in unexpected places but also in the expected places 
Good luck!
p.s. looked out of curiosity: Sarah Lawrence has a guitar ensemble, a guitar recital on the website, and a program in Italy that includes classical guitar but I had trouble finding who teaches https://www.sarahlawrence.edu/search/?q=classical+guitar
Yale School of Music has a guitar program but you would most likely study with a grad student- though maybe not.http://music.yale.edu/study/degrees-programs/guitar/
Juilliard has Sharon isbin. Not sure where Davis Starobin is- used to be Curtis I think.
