We are planning a road trip flying into Phoenix, and flying out of Las Vegas 6 days later. We want to spend at least 1 day at the Grand Canyon. We would appreciate any recommendations along the way of must see sights, accomodations, and restaurants. We are traveling with my parents, they are in good health but do not hike. Any specific tour companies recommended of the Grand Canyon? We do not plan on spending any time in Las Vegas other than to fly home.
