ConfusedandUndecided

I apologize beforehand if this topic seems to be repetitive. I could really use some advice, though. I have been accepted to MIIS (International Policy Studies with a concentration in non-proliferation studies) and Elliot (Security Policy Studies). Since I received a scholarship from MIIS, the costs of attendance at both institutions are exactly the same. However, MIIS also offered me a free summer at Middlebury College to study Arabic. Here is my dilemma. Is the opportunity to get a high degree of proficiency in Arabic at MIIS worth to decline the offer from Elliot, which is, as far as I can tell, a generally higher regarded school? I would appreciate it if some people would share their thoughts about this. Another question: Since I am an international student, do you think that the location in D.C. would have less significance for me than American students? Thanks for your help. Any replies are very much appreciated.
