Walt Disney World Resort in Florida is over 40 square miles (104sq km). It is made up of Magic Kingdom, Epcot, Disney’s Hollywood Studios, Disney’s Animal Kingdom, Disney Springs, Typhoon Lagoon and Blizzard Beach, as well as the hotels. Magic Kingdom alone is 142 acres and split into six themed lands. So, use your common sense; take comfortable shoes (more than one pair), schedule downtime and allow for transport logistics. Have a loose plan of what you want to see and do so you are not constantly hopping from one park to the other.
