My campus had over 95% of students on campus due to limited off campus availability. I went to a school of 1300 and undergrad only. I LOVED the dorms. I loved that I could walk across the street and see any friend I wanted. It was great. Now that I'm living in an apartment after graduation, I really miss being able to walk down the hall or just down the block and see whoever I wanted.

Make sure you buy/have mouse traps if you live near the commons food areas. Damn mouse ate my ramen.

Oh, and a vacuum! I had a cheaper one that my parents bought for me and I LOVED having it in the room. It made life so much easier.

Earplugs/eye covers too. Oh, and posters! Lots of posters! My minifridge (I have one of the taller 3 ft ones) and my microwave were a life saver!
