I've had my netid and enterprise for about two weeks now. It was pretty painless, but you need the official acceptance first.
I'm also trying to decide between on and off campus housing, and leaning toward the former. I'm coming from abroad so I can't visit ahead of time, and I am leery of signing a lease without seeing a place. From what I've seen, Goodwin-Green apartments look much nicer--and more expensive by ~$200/mo--than the others. Location for me is important since I will be carless. It looks much easier to get around campus from Goodwin-Green, and a relatively short walk to downtown Urbana. By contrast it looks like a 15 minute walk to get my department from Orchard Downs, and longer to get groceries. Judging by the schedules, bus service from there doesn't seem very convenient, either. Any insights from from the forum would be appreciated!
