I'm really struggling with this decision as well.
I'm on the waitlist at Harvard MPP, but will likely not attend because 1) no money and 2) Harvard doesn't seem to care if I attend or not. This is the feeling I get from having interacted with their admissions office, or perhaps more accurately, the lack of interaction I've received from said office.
Meanwhile, I'm in at Fletcher MALD with ~30k over two years, and Fletcher's staff has been courting me regularly ever since I got the letter of acceptance. Everyone from Fletcher has been exceedingly friendly and open. Still, I'm having a devil of a time bringing myself to sign the papers, knowing that I'd have to borrow around 100k to attend even with the generous offer.
Can anyone advise me here? Is Fletcher worth this kind of debt? I know this question is personal to a large extent, but any input would be very much appreciated.
