Unfortunately I was only there for Thursday because I went to Penn's ASW on Friday/Sat. And I missed the bus tour and dinner to meet friends in the city. But I was under-impressed. The classroom one panel was in seemed old and dingy. The current student panel had a grad from '91! He is not current. I did however like the free gym and opportunities DC offers for externships, etc. Living in Gewirz seems convenient but since GULC is in a business district and not a residential neighborhood it may be lonely/sketchy walking home at night and you would probably feel trapped at school 24/7.
I loved Georgetown coming in to this weekend but after a pretty medicore ASW experience and a much more impressive one at Penn, my decision became more confusing after visiting.
So basically, you checked in, listened to the brief intro by Andy Cornblatt and the other deans, went to the Q&A with students, and left? You missed out on a LOT. I thought the law library was amazing, LOVED the fitness center, and really enjoyed the second day's events. The Mock Supreme Court case presentation was really fantastic, and Day 2 really gave me a chance to hear from and speak to the faculty and staff, all of whom really impressed me. I think the office that runs the clinics also offered a breakfast with admits and I heard that people who went to it got some good one-on-one Q&A time.
Sounds like you were in my Q&A group... were you also in 1-10? I really appreciated the cross-section of current and former students, personally.
But I also realize that GULC isn't for everyone. I love the fact that it's so big, because a) it's got its own campus (and, as such, would feel really uncomfortable for me if it were much smaller), and b) even a HUGE law school is still much smaller than a really small undergrad. I was really impressed with the current students I spoke to, and of the other admits I met, the ones I liked the most were pretty much decided on Georgetown. But that only means that it's a great fit for me... it's definitely got a strong "personality type" that isn't right for everyone. Ironically, after I left GULC's Open House, I went to another school's ASW and wasn't impressed by much, but I did meet one woman professor who I really liked. It wasn't until afterward that I read her bio and found out that she, too, got her JD from Georgetown. That was the nail in the coffin for me.
If you really were leaning toward GULC before the visit, know that you missed out on a LOT. I can't speak to the merits/demerits of Penn (living in Philadelphia has never even crossed my mind) other than to admit that it's obviously a great school, but if I were in your position, I'd definitely try to get another visit in before making a final decision.
