We have someone joining us for our trip in the middle of our week. It is a friend's mom and she is not familiar with flying or being in situations far from home. She doesn't have, and doesn't understand how to use, the Uber or Lyft app. We booked her to John Wayne and she will have no issues asking airport staff how to get to get shuttle/ cab area. I am thinking one of us will need to Uber to the airport and pick her up and then Uber back. The only other thing would be telling her to find a cab, are there still cabs waiting or is it mainly Uber/Lyfts and shuttles?
