Might depend how far you’re comfortable traveling daily. We’ve done Cottonwood Pass to Chicken Springs Lake (overnight 1); to Rock Creek (overnight 2); Guitar Lake (overnight 3). Heading out over Cottonwood Pass to the PCT makes this 4 days, 3 nights from Whitney with some great hiking. Car shuttling took some planning. Overnighted in Lone Pine before setting out. Also several options along the way to shorten or lengthen individual days as you might need. We didn’t find a 2 night trip…I’d also be interested if ideas come up!
