Review concerns Uber only, Uber dropped two of us at Venetian from Vdara, we retuned on same route at busier time via cab and paid less in cab than Uber.?!Also not able to enter Hotel promo code. Next day ordered Uber from downtown to airport. Same problems as no Promo field in app. Driver picked up another couple or running a scam and wife and I were left stranded. They billed me for trip. Their customer service leaves a lot to be desired. Must be located in a foreign country somewhere that did not understand what I was telling them. Answered by individual w names I cannot pronounce. Will never use again. Took me half a day and many emails trying to convince them that they picked up the wrong fare. Not a very truthful driver.
