Wife and I made the permanent switch to Lyft a few years ago. It has never caused an issue for us in/around WDW. With Chase Sapphire, we get: 10X points on rides and Lyft Pink free for a few years (free priority pickup upgrades, 5% off standard rides, easier cancellations, etc.). Ultimately, that's the real reason we only use Lyft, prior to that, we never had an issue with Uber, but did 'feel' as if Lyft was cheaper more often.
