We did a long road trip last February through PA and NY, aiming for 7 schools in 5 days but only hitting 6 because of weather. We live in Upstate NY so Skidmore, Bard, Vassar and Hamilton were all day trips. The big road trip was Lafayette, Lehigh, Muhlenberg, F&M, Dickinson, Bucknell and Rochester in that order (Dickinson was the one we couldn’t work out - 3 tries to reschedule over 2 days but we had to keep moving). A few of those probably won’t work for you (Bucknell has a huge Greek scene) but the general route may and you can try to hit Hamilton and maybe Skidmore or Bard on your way back to I-90.
