<p>I'd like to take this chance to urge everyone to attend an Admitted Students program, especially if it contains an overnight program.</p>
<p>I can only speak for Columbia, but having seen several different sides of that process, it is valuable in many, many ways. For example:</p>
<p>1) The prefrosh who bother to show up to such things are much more likely to be attending, based on their (obvious) interest levels, so their opinions will matter more to you and they're a good cross-section to meet.</p>
<p>2) The people you meet at Days On Campus form the start of your freshman-year friend network. Maybe a quarter of the people I met when I arrived for orientation had attended Days On Campus, and had several friends, which made much easier to meet more people faster. A bunch also attended an Outdoor Orientation Program where a group of incoming first-years would bike, swim or hike together for a week, ending up in NYC together. These connections they made gave them a leg up in filling the hectic social vacuum that exists during orientation - not that there's a lack of social life, but people start out lonely and there's a feeding frenzy to make friends.</p>
<p>3) When you stay overnight, the students hosting you will give you the real deal. They'll be actively interested in answering the real questions you have, with real answers. You'll meet enough of them to get a sense of the atmosphere and attitudes on campus (unless you're unlucky and get some whackjobs).</p>
<p>My freshman year, everyone who hosted someone on my floor got together and we hung out, met the prefrosh, some of us went around campus or even the city with them. My senior year, admissions was hard-up on space for all the interested kids to attend Days on Campus, so when I offered my 5-bedroom dorm apartment they dumped 8 kids on me, and 6 more on the girls down the hall. So we threw a party. Got at least two of them laid. These things can go all over the spectrum, but basically everyone who stays overnight, and escapes the scripted propaganda-based sessions drummed up by admissions, gets a close-up peek at what life is really like. At least, that's true for my school, and I imagine it's true for others as well.</p>
<p>If it's a stay-overnight deal, it's well worth the cost of transportation. You'll learn a ton, and probably have a lot of fun. Don't pass it up if you can make it.</p>
