we got into the cab at 00:24 at the LAS airport, and asked the driver to send us to Excalibur hotel, he said ok. We checked the route with google that the distance should be around 3.6miles, and no traffic, however, on the middle way, we suddenly found he drove on another way, and the final distance is 7.8miles, and we were charged $30, when we doubted him, he pretended he could not understand us. what a crazy driver!
