Just gonna address the meal plan one but I would suggest getting all dooley dollars. I’m not a big fan of the DUC food so I always just eat in Cox which I think is significantly better. And you can still get into the DUC/DUCling with dooley dollars. Also it was easy to sneak into the DUC but now that we have the DUCling it will probably be harder.
Our D lived in Woodruff sophomore year (she graduated in May.) She got a great suite with 3 friends and liked being near Lullwater Park to run but by the end of the year she wished she had stayed in Harris. Harris was renovated the summer after her freshman year, so she could elected to stay there as a sophomore. Many of her best friends ended up in Harris (she had roommate issues later) and it’s more centrally located on campus, so she spent a great deal of time there in the end.
The negatives about Harris are the communal bathrooms at the end of the hall (don’t know if the renovations changed that) and smaller rooms. Perhaps sophomores get first crack at the nicer rooms? Woodruff had a communal kitchen on the first floor, a small cafe with a piano and a workout room (or it did when our D was there.)
D preferred Cox to the DUC as well. I think she kept the full meal plan since until junior year, when she moved to an apartment the last two years.
You want to be in Few or Evans. The location is far better than the other two, they are much newer, and the social scene is much better. Harris is on the other side of campus and a long walk from everything except the library. All the clubs, teams, etc are housed in Fevins, so Harris tends to be heavily international and less cohesive. Woodruff is barely on campus and used mostly for overflow - strongly recommend against it unless you have a car.
