<p>How long does one visit take? I am visiting Princeton, MIT, and Stanford soon, so I need to plan the trips and stuff. What all do you do on a college visit? Take the tour? Do colleges have tours going on at all times? Do you sit in at classes? Meet students? What are you supposed to get out of it?</p>
<p>Most important, again, how much time should I leave for each college?</p>
