No, the Walt Disney World Monorail system does not serve all four theme parks. It specifically connects the Transportation and Ticket Center (TTC) to Magic Kingdom and EPCOT. There are three distinct lines: the Express Line (TTC to Magic Kingdom), the Resort Line (stopping at the Contemporary, Polynesian, and Grand Floridian resorts), and the EPCOT Line (TTC to EPCOT). If you want to visit Disney’s Hollywood Studios or Disney’s Animal Kingdom, you cannot use the Monorail; you must use the Disney bus system, the Disney Skyliner (for Hollywood Studios), or watercraft. For 2026, the Skyliner has become the primary "highway in the sky" for Hollywood Studios, while Animal Kingdom remains accessible exclusively by road. Guests staying at monorail-access resorts can easily hop between Magic Kingdom and EPCOT by transferring at the TTC, but a trip to the other two parks will require a different mode of transportation.
