Especially some of the programs interviewing that weekend - Iowa, Uva, CMC, etc... yeah, I'd gladly drop the cash necessary to have a shot at one of those places.
Seriously, Therecanbeonlyone, I don't think any program would hold it against you. If you cancel as soon as you find out, then you are doing the best you can under the given circumstances. Hopefully, you'll be able to defer, and the point will be moot... but I wish you the best of luck, man... because if I had to worry about all of that on top of everything else, it'd probably push me over the edge... of course, remembering that I was debt free would probably bring me back.
Yeah, one other thing that I would like to see is all of the programs come to an agreement that all interview invites be sent out during one hour each day, so I'm not compulsively checking my phone like a freaking idiot all day... OK, so that's probably more of a "me problem", but I'd still like to see them make the change...
