My sister Mary and her husband leave for a trip to the American Southwest on Tuesday. She has planned on spending one night at the Grand Canyon Lodge (South Rim). Then they have a free night before they arrive in Las Vegas for a short stay and their flight home. So they have one free night between these two locations. Any suggestions for a good detour and overnight stop? They have never been in the area but Norm isn't interested in a marathon drive.
