Hi Kimberly, Disney does have free park to park transportation, though this is not always by bus. For example, to get from the Magic Kingdom to Epcot (and vice versa), you'll take a monorail. And to get from Epcot to Disney's Hollywood Studios, you can take either a bus or a boat. There is free Disney transportation in the morning prior to park opening for guests who have early character meals. But if you have access to a car, I would strongly recommend you use that to get to arly morning reservations. If you take a bus, you may be waiting around a while for it to arrive. With a car, you can just go with no worries. Good luck with your planning. Please let us know if we can provide additional assistance.
