I am on the same boat here...
I got into Fletcher (10k), Columbia (20K), Sciences Po double degree with Georgetown and the graduate institute with scholarship and a stipend. I think that the graduate insittue would be a great choice for the location, but I realize that they have some institutional problems sucha s having different locations throughout geneva university... I have to consider the financial aspect as well since I am international without a substantial amount of money to pay for grad school.
I heard the same thing about the institute. The development track that joined the institute quite recently is not as strong as the other programs (MIS and MIA).
boa sorte pra todos...
