I have very mixed feelings about this issue. I'm finding it really difficult letting schools go (except for one) without seeing the financial aid package and possibly doing a look-back. Also, I've invested quite a bit of money and time to interview at these places so I feel like it's my right to hang on to them as long as I want. However, I do understand the POV of being considerate to other applicants (which is why I'm conflicted). I wish I had a "top choice" like many applicants, but I don't, and to me, each has its advantages and disadvantages (location, cost, rank, having to consider my partner's career, etc).
