We were in Vegas in December and used Uber/Lyft services for the first time. We used Lyft. They have more drivers in LV than Uber.
We were VERY happy with the service. Clean cars; friendly, articulate drivers. Take the most direct route (via Lyft GPS) and were there literally within minutes of our call. Cheaper than the cabs. Closer and quicker than taking a bus. Designated pickup/dropoff areas at each property. Recommended by the belldesk/doorman as the way to travel; and they make no tips from Uber/Lyft rides!
We could not have been happier. (We have had many bad experiences with cabs in LV.)
