<p>well when I went, check in was at 8am and the day finished around 6 or 7pm</p>
<p>The first day starts at 8:00 am, and the flier said not to plan on leaving the second day until 5:00 pm. It said something like, "unlike prior years' sessions, students should not plan on leaving before 5:00 pm on the second day of Preview".
