well a couple of things..
1-You won't have any help from the OLs and Movers&Shakers to move your stuff to your dorm. It will also take longer because you will also not know how to get to your room depending on which side of the building you're living in.
3-Miss OL and other students in OL group
4-Miss signing up for swimming test if haven't already
5-Miss picking up a folder (from what I can remember) that had a bunch of info for you
Maybe that was more than a couple of things. But considering all that, it may not be too bad...hope that helped
