It is always a pleasure to fly into Charlotte Douglas Airport. The crew are much friendlier than neighboring airports in neighboring states. The food options are plentiful. Bathrooms are kept orderly, for the most part, and very user friendly.
You can easily catch a cab or Uber from the airport, but Uber tends to be much cheaper! The main terminal is huge and the rocking chairs in the lobby are very relaxing.
If you get a chance to land in Charlotte, then make sure to take some time to explore the local cuisine.
