So I recently spent 2 weeks in Vegas.
Being from Calgary, where we only had Uber active for a couple days, I hadn't had the chance to use it but had the Uber app ready to go. I used it on my first day in Vegas to stock up my room with groceries. Only then I learned about "Lyft", another Uber-like app alive and well in Vegas. I'd never heard of it but most Uber drivers in Vegas also drive for Lyft and seem to prefer it. The driver gave me a code which gave me $5 off my next 10 rides.
I used up my 10 rides over the next two weeks and spent about $50 total (including tips and the $50 discount). Had I taken taxis I'm sure I would have spent $200+ so it was a savings for sure. The taxi from the airport alone (to Bally's) gouged me for $24. I also learned Lyft (and Uber) pick up from the airport, so I'll also use them in the future as their rates are way cheaper than taxis even without $5 off per ride.
The code PETE251738 will work for anyone that hasn't used the app, just enter the code (tap top left icon -> select "payment" -> enter into "add credit code") prior to first use and you're set.
I wasn't sure if wait times would be affected but they're all over Vegas so it was always just a few minutes. Very easy to communicate with the drivers too to set up special pick up spots. Enjoy and good luck crushing the games!
