My preferred time frame for most cascade climbs is 1.5 days. Drive to TH, hike in to camp the afternoon the day before the climb then have a lavish dinner with copious amounts of liquor. Next day, climb at a leisurely pace and hike out with plenty of daylight left.
I unfortunately don't have that luxury very often. Car to car, Seattle to Seattle climbs in a day often result in a dangerous bleary eyed drive home. Thank god for those vibradores on the side of I5
