calgar- Actually, you don't have to worry about whitehead since the Carolina Inn bought the land and is going to knock it down to build suites. BUT whitehead is actually awesome- the rooms are huge (Getouttabuffalo can attest for this also!) and good for.. certain activities
Honestly, I think suite style is a lot more social than hall style (North/Mid Campus) just because of the south campus atmosphere. Suite doors and room dorms are almost ALWAYS open and ready for you to mingle/hang out with friends. And there are always people just hanging out outside by the balconies... And plus, nothing beats all the kids in the big South Campus dorms (Ehaus, HoJo, Craige) running outside to yell "TARRHEEELSS" after we win a basketball game
It's a lot of fun, and (at least I've heard) come March it's absolutely crazy with basketball season in full swing since it's right by the dean dome.
And totally agree with cloying- not having WiFi in your room really isn't a big deal at all because of the ethernet. If you have a room close to the study lounge, then you probably will have WiFi (I do).
