We stayed in Williams and rode the train. It was enough time to walk around and see parts of the canyon but unless the food situation has changed, where the train stops there is only one place to eat and it was too crowded and slow service. I didn't see that many places to eat while we were there. Driving to the canyon would be best if you have the time to spend a couple of days to sight see. We really wanted to take the ridding tour down into the canyon but the tours were all filled. It was breathtaking but I noticed most of the children there were bored just looking and not having a great time and wanting their parents hurry up and look. LOL
