What time to show up for overnight?

<p>I have an overnight visit tomorrow night (a Friday), and I know we have to be there at 4:00, but is there any reason we should come earlier? I’ve already visited the school, but never for an overnight.</p>

<p>I could go to a class, but it would be very early, and then I would have nothing to do from then until 4:00, so I don’t think that’s a good option.</p>

<p>Any suggestions, or should I just go at 4:00?</p>

<p>Go to a class- there’s always something to do until 4.</p>
