Allow two days for the South Rim, unless you just want to drive the rim, not hike it. Then Wupatki Natl Monument just north of Flagstaff. And since its right next door, hit Sunset Crater NM. Then to Walnut Canyon NM. Depending on how much time is left, you could fit in Petrified Forest NP. Then come down through Heber, Payson, etc to Scottsdale and hit the Pavs.
