Driving from S. CA to Flagstaff, Grand Canyon and Sedona

Should be high 50s during the day and low 30s at night. No snow is expected. Actually, it is a little chilly but gorgeous up there now. Coming from Ca, I would go I 10 to 17 north, or you can go though Kingman to the 40. There is a nice KOA in Williams that has some " kid " stuff to do.
The RV park in Sedona, Rancho Sedona I think is right on the creek. Friends were up there last weekend. Just bring layers of clothing and you will be fine. Roads are fine now. No snow on any main road at all. Have a great trip!
