If you don't feel safe at that hour using an uber, Mears Taxi is on level two of MCO by baggage claim. They have a contract with MCO to use their platform. When you leave the terminal to go to the car rental garage, make a right before you cross at the traffic light and you will see the mears taxi cabs and other taxi companies lined up 24 hours a day. They don't allow ubers/lyfts there. This may make you feel safer. (Use Google Maps and click on the road to see photos).
