It doesn't hurt to ask to schedule your interviews closer together.
I called a school yesterday, about this possibility as I was going to be on the East Coast for an interview for one school. The admissions people are pretty understanding and it seems like they will try to accomodate you.
I think if they have a good idea that you will be interviewed, you will basically find out then, but if not be prepared to hear the say your file is still under review or that your rejected(hopefully they won't be too callous).
But definately ask them about it. That' s my advice. If anyone else has an opposite opinion, please chime in.
