The only reason is to get our skiing in at the first part of the holiday - hubby's request, not my choice !!Your trip kind of has a lot of loops and spots where you'd be back tracking, or driving right by one place, and then going back to it at a later date. For example, it would make a lot more sense to try and fit in Bryce and Zion before you go to SLC instead of backtracking there from the Grand Canyon.

Coming to Flagstaff from Cortez - won't go into the Grand Canyon until the next day when we then head to the campground at Williams for the next two nights- it is apparently only an hour out.Your nights at the Grand Canyon, staying in Flagstaff and Williams are kind of far out from the park, and are in the wrong direction from where you are coming from/going to.
