My husband and I are making a 16 day circle trip to Arizona and New Mexico next month. We plan to drive from santa Fe to Monument Valley ( gouldings Lodge). On Map quest, that appears roughly 7 hours. Does that sound right ? Are the roads good ? Is there scenery ? Too much in 1 day? I would like to get there before sunset, and we wish to stop in 4 Corners Monument. Thanks for any advice !
