We use taxis when staying at the WDW resorts instead of Uber, Lyft or Minnie Vans and we have frequently been given the big 15 passenger vans. I never feel bad about it since they are getting a fare instead of sitting idle.
We had trouble this summer, though, getting a taxi that was willing to travel from WL to GF. We had to wait about 25 minutes for one since no one wanted to take a fare such a short distance. They told us that we should have used Uber or Lyft instead since we would have gotten a ride sooner from them.
