Enjoy your trip. There are great photo opportunities all over the place at Grand Canyon. There are somenice views behind the lodges on the south rim. Also, the Desert View Watch Tower is a great photo opportunity. If you have the time, definately take a hike into the canyon. Although with limited time, you won't be able to go far, it's a whole different experience below the rim. Check out either the Bright Angel Trail or South Kaibab Trail. My son and I spent the night at the bottom of the Grand Canyon 3 years ago and it was amazing.


As others have said, early morning or later in the evening are best for light and colors.


You said you are staying an hour outside the park. If your plans are flexible, dotry tostay inside the park. It can be difficult to get in the El Tovar (when we stayed there we booked a year in advance). But you might get lucky at the Kachina or Thunderbird next to the El Tovar. Both also right on the rim. The Bright Angel is also next to these two.Staying at one of the lodges on the rim gives you a great opportunity both before/at sunrise and sunset. The extra time available at the parkwill also give you more of a chance to explore below the rim.
