I'm planning a roadtrip starting in Phoenix and ending (most likely) in Denver. We will be travelling from Tuesday morning - Saturday night before flying home to DC. Only place that we're set on seeing is the Grand Canyon, but there are so many others that we would love to see. The issue that we're having is figuring out the best game plan for what to see and how much time we'll be in the car. I'd like to not drive more than 3 hours/day and would prefer to do less than that.

Any suggestions??
