Yes, Walt Disney World provides direct bus service between Disney's Animal Kingdom and Disney's Hollywood Studios. These "Park-to-Park" buses typically begin running in the early afternoon, usually around 1:30 PM, to coincide with the start of Park Hopping hours. The bus stops are located in the main transport hubs outside the entrance of each park. It is important to note that unlike the Magic Kingdom and EPCOT, which are connected by the Monorail, or EPCOT and Hollywood Studios, which are connected by the Skyliner and Friendship Boats, the only free Disney transportation between Animal Kingdom and Hollywood Studios is the bus. The ride takes approximately 15 to 20 minutes, depending on traffic. If you are in a rush and don't want to wait for the bus, a "Minnie Van" (via Lyft) is a faster, albeit paid, alternative.
