Terrible seats on the coach. All the seats on one side of the coach downstairs are eye level with the bottom of the window so we couldn't see anything unless we stood up. Driver decided to swerve for effect by where previous cars had gone off the road just before the Hoover Dam, and my friend went flying. Also had no choice where we sat, staff were not happy when we refused to sit in seats going backwards for three hours, hence no tip. Also nowhere on earth enough time there to do the place justice.
