We stayed at the lodge at the North Rim. It was very nice and you should consider this. On the way out we drove to Point Imperial and Royal Point. If you were able to see only ONE of the North Rim sites, it should be Imperial. You won't be disappointed.

I loved this place because it was simply beautiful! Arizona is a gorgeous state and the grand canyon makes it even more better with the spetacular views and wildlife they have there... It's awesome!

The Grand Canyon is a gorgeous place to visit. The best place to see it is on the North Rim. I have been there several times, and it was more beautiful each time.
The last time I went it was raining. That was definately worth the trip. There was fog down in the canyon. Then the fog started to lift and it was absolutely gorgeous. I would definately recommend going there even on a rainy day!!
