Just returned from DLR. I downloaded both Lyft and Uber, but Uber gave us a superior discount so we went with them. FYI, here is what we got and what we paid:
SNA to Grand Californian Hotel: Uber XL for 5 people. Cost = $34; new rider discount $22 (when you first sign up you can use this: code is feeling22). Final cost = $12. Very new Kia Sorrento. Driver friendly and fun. Arrived to pick us up right outside baggage claim within 7 minutes, helped with luggage and super easy.
GCH to SNA: Uber XL. Cost = $31.78; used new rider discount again (daughter's phone) for a final cost of $9.78. Brand new Toyota Sienna, stocked with waters! Driver courteous and easy going. Arrived in 7 minutes, helped with luggage, drop off easy as could be.
I'm sold! As nice or nicer than a taxi, cheaper, and so easy. Lyft had a "first ride free" promo but it automatically uploaded a $50 discount that gives you $10 off on each of 5 rides. Don't think I'll be using it again before most of those expire. Uber's discount gave us $44 off instead of $20 so the choice was easy.
