Several chain hotels right at the exit for Meadville on 79. We stayed in Erie (at "Big Sister's Bed and Breakfast"

) and drove down in an easy 45 minutes.
Don't know what they do for transportation when visiting. If your student ends up attending there, though, there are a bunch of "locals" up and down the east side of PA, and I'm guessing there is probably a "ride" board. And I know the violin teacher lives in Erie.
