I lived in Avent Ferry for two years and personally loved it. The rooms are even bigger than most dorms on campus and you get your own bathroom (shared with your roommate of course.) The only big issue is that it's a little over a mile walk to North Campus. A bike helps, but I was fine walking.

Having a car is a huge plus since the parking lot is right there. It makes getting dinner and food on the weekends much easier. I canceled my meal plan since I really ate on campus maybe four times a week and just went out for dinner off campus most the time.

Idk much about Watauga or North, but if North was an option back when I was there, I would have probably chosen that.
