Getting interviews will depend on how good of a candidate that you are going into peds.
As far as distance goes, I'm not sure what Febrifuge means when he asks "How are you going to interview at these far-off places?"--just fly around and interview where you want. I just finished up with my interview season and flew everywhere that I wanted and did not limit myself by geography. Just be sure to take out extra loans.
As for away rotations, you can only do what you can do. Think of it this way, you would probably only be able to do 1-2 away rotations anyway if you were able to do any. I'm sure you will be applying to more than just 1-2 programs. So, if you had done away rotations, they probably wouldn't have influenced the other programs that you would look at where you didn't do an away rotation. In short, if you can't do away rotations, I wouldn't worry about it too much.
You will definitely have to answer the question, "Why do you want to come to Arizona [cali, etc.] over and over." Programs will want to know why you would want to leave your "home" to venture out West, so just have good reasons for doing so other than saying, "Well...you're accredited, and I saw you were taking residents."
