I may have a friend come to the Portal just to shuttle us down to Lone Pine. Now, how to make sure he is there when we get there. Can he camp at the walk-in sites the night before even without a hiking permit? If so can he hang around the Portal waiting for us? They do have "Day use" parking he could use without a parking permit, right?

I guess he could get a walk-in Whitney day hike permit but he won't be hiking so if not necessary why bother? However that might provide a parking permit. As I asked before, maybe he can use day use parking.
