<p>Yes, there are lots of tourists in Harvard Yard; they affect…other tourists the most, in particular those who are doing the tours (but do not consider themselves tourists). Although they can get in the way of students going to class or locals trying to get to the T station by the shortest route, cutting through the Yard, the crowds are a very minor irritant, a fact of urban life. S and his friends appreciate the density around Harvard Square.</p>
<p>I would not make it a factor in deciding whether to attend or not (but then S decided against some colleges because they were too suburban).</p>
