I'm sure it depends on where you go. Mine was pretty fun, we had a lot of presentations from deans and professors, met our academic advisers, watched a few movies. Then we had a lot of social events, a cookout, dinners, games with small groups of kids etc. At night they pretty much let us do our own thing so we got a crew together and walked around DC and went to a hookah bar. We stayed in the dorms, so we got a taste of what it would be like to live there with everyone next year. All in all I had a great time. Don't sweat trying to meet every single person; your head will explode remembering all those names. Just remember everyone is in the same situation as you, be as polite as possible and it won't be too awkward.
