Some would be much more difficult to reach than others. The problem isn't really the distance, it's the weather. I don't know what the height amsl the North Poles are, but could be significant - meaning that you wouldn't be able to get high enough. There wouldn't be any rescue services provided, so you wouldn't need to worry about being able to get in touch with any of them.
