All of this is also what I am sensing: Georgetown would be more in line with my conflict resolution interests, particularly in terms of Colombian conflict.
Columbia seems amazing overall, but the professors at the department don't appear to be doing the kind of work in which I'm interested. Granted, I might be able to tap into Columbia's resources at SIPA, etc. Geographic proximity to my significant other is another very big factor and Columbia wins that round.
In terms of my career plans, I hope to follow up an MA in Latin American Studies with a law degree, and work in human rights law (perhaps for OAS) or international arbitration (totally different bent).
