My family is wanting to plan a roadtrip from Tennessee to The Grand Canyon for the week of July 12-20. We have 2 boys ages 8 and 13. We would like to make a stop or 2 in route and something fun for the kids at or near Las Vegas or the Grand Canyon. Any advice would be greatly appreciated. My husband has visited the Canyon multiple times as a child and says it wasn't ever enjoyable because they drove and drove, arrived, looked at the canyon and left. So we are looking for activities to make it more interesting and memorable.
