The five-star rating is simply for the well-marked and very specific direction signs directing people to return their rental cars. My husband was worry about returning our rental car at the end of our trip as the rental center is not located right at the airports many car rental places that we had previously used. There were signs on the highway and once we got off the highway, there are signs clearly marked along the streets. They even tell you which lane to be in. This is extremely helpful since Las Vegas has many visitors from all over the U.S. and the world. I am not afraid to admit that I lose my sense of direction when driving in unfamiliar places so the signs giving exact instruction are very helpful.
