Parking for campus tour - Queens College

My son is registered for a campus tour at Queens College next week. I cannot figure out how to get him there unless we drive, but I have been told it is really hard to park there. Is this true? Is there any other reasonable way to get there? We live in Westchester County. For Brooklyn Collge, we just took Metro North to Grand Central and the subway, but Queens College does not appear to have a subway stop. Do the students all just drive?
