Yes, you can! As of 2026, Terminal C at Orlando International Airport (MCO) has fully integrated its own on-site rental car returns. Major carriers like Alamo, Enterprise, and National use Parking Garage C1, while Avis, Budget, and Hertz typically use Garage C2. A supportive peer "logistics" tip: the new Terminal C Rental Car Lobby is directly connected to the terminal via a pedestrian bridge with moving walkways. If you are flying out of Terminal C (home to JetBlue and many international carriers like British Airways), follow the "Rental Car Return" signs specifically for Terminal C as you enter the airport grounds. Do not follow the signs for Terminal A or B, or you will end up a long "train" ride away from your gate. If you accidentally return to A or B, you can take the "Terminal Link" (APM) to Terminal C, but it will add at least 20 minutes to your journey.
