I would probably ask the secretary what the chances of getting the month you wanted was (compared to last year). Otherwise, I would just be really polite about it and explain there were scheduling conflicts. Most of the time you deal with one of the secretaries when scheduling aways, so as long as you don't wait until the month before to cancel, I don't think you will burn any bridges with the surgeons. But definitely research hard which programs you want to do an away at. I think it is a huge advantage come applying time.
