I did it this summer in one day...not bad. Actually, it's a funny story. We started at 4am...went the wrong way (Yosemite JONG) hiked 5 miles on the wrong trail. Got back to the trailhead at 8:00 and started then. We hiked up beer, video camera, camping chair, red bulls, and wigs. We make a little red bull commercial at the base of the cables. Point of the story, one day isn't bad. I'd recommend going up the mist trail and down John Muir trail. That way you get to see them both and don't have to come down the mist trail when your tired. Ask a ranger or someone who knows about the spring above little yosemite valley, bring something to treat the water. Have fun.
