Oh it's not that bad. Our driver Art, picked us up at a taxi stand at Planet Hollywood and thanked us for taking him to a destination off of the strip (the CES convention had just ended and everyone was on their way out of Vegas--luckily, we were just on our way in). Art is what I would describe as a middle-aged, modern day Cheech and/or Chong. He was so friendly and entertained us with stories from his life in 80's living in San Francisco for our ride to the rental car company.
Is it expensive? A bit. Did our van sound like it was going to shake itself into tiny little van pieces when we got onto the highway? Yes.
Who cares? In the end, we safely got to where it is we were going and had a very memorable experience with an awesome guy.
Can't say how they are when calling into a dispatcher. Also, if out driver wasn't so awesome, I would probably drop it down to 2 stars for the quality of their vehicles.
Art, this extra star is for you! I hope you see this one day! Thanks for the ride!
