We did Uber from Denver international airport to Aurora. It was our first time using and we were very unsure about the whole process. It was so easy. We had a very nice driver. We could have gotten to our destination quicker by paying a toll fee. Our driver informed us of our choice well in advance. We didn't take the toll. And we would make the same choice again. We were very impressed. Then I got the charge!!!!! I thought they automatically applied my $20 credit but they don't. When I contacted them they said you have to put in your promo code before the trip ends. I didn't ever see that prompt that I remember but then I wasn't looking for it. I had no email showing the promo code. I told Uber this. I read some online complaints and figured I would never hear from them again. Within an hour I got an email from Uber applying my $20 promo. I'm so happy and impressed. I highly recommend their customer service and Uber based on my very first experience. Thanks so much.
