During my week in Orlando, that's right I went to Disney, i had the realization that a 30 minute cab ride with traffic is somewhere around $100. I ain't got that kind of money. So I tried using both services, in order to save as much as I could.
In signing up for Uber and Lyft, there are ways you can get FREE MONEY CREDITS. I signed up for Lyft with instagram code INSTA20, which gave me $20, which ended up being a round trip to Epcot from my hotel, about a 10-15 min drive. Then I referred a few friends and got additional credits. The same worked with Uber, though there was an automatic free ride with signing up, and more per referral. However there are a few things you need to know...
PROS: CHEAP, some really nice drivers. No cash needed as its all through the app-including tips. You can electronically split the bill for a carpool, making it really simple and kind of fun. Drivers and riders are rated by each other in order to keep everyone happy, if your driver score gets too low you are fired, and if your rider score gets too low you cant get rides, so be nice. The app lets you see the car approaching, and even tells you what car to look for and who is driving it. While driving, it shows you the route of the car!
CONS: There is no "meter" on the app, but you can download apps that guesstimate the expense if you keep them running during your trip, I use an app called Meter. The drivers can sometimes be sketchy or rude, despite the rankings. I had a first time driver, which was a little troubling. Luckily he turned out to be nice, but I wish there had been some sort of training period to make sure that he was qualified. He also did not know the rules about payment and toll roads, which customers are automatically charged for through the app. That led to a lot of confusion, and I wish Uber had better handled the training and initiation of new drivers. Also, I pre-ordered an Uber ride, and was given no updates about confirmation or any information until 5 minutes before my scheduled time, and then when my driver arrived it was his first day driving- plus he was new to the country, which was a little worrisome as he barely knew the area better than I did.
I can't say for certain which service is better, but I know a lot of it depends on your location. Some places have both, some have neither, If you're in a place with both, I'd recommend doing what I did and trying to get the most bang for your buck. Cost is pretty similar, and way cheaper than a cab.
