Yet Holes attract electrons, so to speak the hole doesn't actually move, electrons do phyically as it is replaced almost instantly. Not just one electron moves though a conductor, think of how energy is transmitted though those swinging ball thingys.
Example:
As a charge or voltage is applied one electron moves from one valance to a valance hole created by the potential difference. As the electron leaves the valance the hole is created and then in which attracts the next electron given the provided flow. So essencially the holes move the opposite way of electrons, but they really don't physically move the way electrons jump to valences of the next hole.
