This tip can help you get totally free parking from any single one of the four Disney Parks. In my most recent visit to Walt Disney World, we knew that buses would run from Downtown Disney to the hotels, so, we parked our car at Downtown Disney and took the bus to a familiar hotel, such as the All Star Music. We then took a bus from there to go to our park, which happened to be the Magic Kingdom. We did the same exact thing back to end up at Downtown Disney and we then left. This worked perfectly fine, and we didn't even have to pay for parking! Great idea, and it worked perfectly for us.
