In the early planning stages of a trip to DL and then driving to Vegas to visit a relative. It will be me and my wife and two sons ages 5 and 7. We're on the east cost and have not been west. Any recommendations for the drive to Vegas? Anything worth stopping at along the way? Should I detour onto Route 66? I don't mind taking some time for the drive there. Once we arrive in Vegas, do you have any recommendations on what we can do as a family? How many days should I plan on for staying there. Any hotels better than others for kids? Thanks!
