<p>If I'm not mistaken, Princeton's days are listed as April 12-14. Does this mean three separate one-day events or is this one three-day event? Which one?</p>
<p>It is one 3 day event. You arrive on Thursday, spend thursday and friday night, and then leave on Saturday, with all kinds of activities for you inbetween.</p>
<p>If you just want to visit for one day, and have slightly less programming, then you can visit at an alternate date, which is later in April.</p>
