We use Lyft or a Minnie Van when in WDW. It's usually around the $40-50 range. Here's when we use a Minnie Van:
1. Going to/from MK - they drop off/pick up right near the entrance.
2. Going to/from Hoop Dee Doo Revue - drop off/pick up at Pioneer Hall.
3. Going to/from Disney Springs.
Sometimes we'll splurge on a Minnie Van just because, but most of the time it's to/from the places listed above.
I generally like Lyft, but we have had some sketchy drivers. Lyft has a nice drop off point for AK (right at the entrance).
