Planning a trip in late August with the family from Sussex, WI to Yellowstone. I really need some help figuring out: how long to drive each day and then where to stay; what stops to see along the way and how long to stay at each, once in Yellowstone where do you start??? Route to take in Yellowstone, where to lodge (don't want to camp). We have about 9 days for this trip. Any and all suggestions are greatly appreciated!!
