Boston University vs. George Washington University

BU would cost me 65k for all four years, and GW would cost 115k for all four years. I like both, but I was hoping to get more money from GW because I wanted to major in International Affairs, and I love Washington, D.C. BU is clearly more affordable and Boston is still a cool city. I feel like I appreciate GW’s culture more than BU’s. If I go to BU, I’ll major in Political Science. Does anyone know anything about BU’s polisci or IR programs? Any thoughts about the schools? All input would be appreciated.
