Depends on where we are going, when, and how much we are pressed for time. We have used the occasional Uber but for the most part, we rely on Disney transport. As others have said, if you are staying on property, you are paying for that amenity already and might as well use it. As long as you plan plenty of time in advance, it's usually no big deal.
But one thing I've stopped doing as much of over the years though is chasing food at Disney. We tend to make plans so that we're not caught up in all kinds of travel mazes. If we are planning an Epcot day, we eat there or at the Epcot resort area. If we are planning a MK day, we eat there or on the monorail, etc. We tend to do Disney springs or 'out of the way' resort dining on non-park and travel days when time is not so precious.
