if you are only moving them 8 feet, and have the ability, i would just screen them in one evening, after everyone comes home, and move them the 8 feet.
leave the screen on, and the next day remove it, or keep it on for a day and then remove it. when you remove the screens prop or leave them near the entrance of the hives, this should be enough for them to reorient.
also like perry said about moving them if they are clustered.
if i had to move bees when they were clustered, i think i'd wait until warmer weather.
good luck, and let us know!
