Disneyland is to Disney World as Lake Ontario is to the Ocean.The most notable difference between the Walt Disney World Resort in Central Florida and the Disneyland Resort in Anaheim California is the size. When making this comparison, there truly isn’t one. Disney World dwarfs Disneyland in size by miles; 43 square miles to be exact. Where Disneyland sits on just over 500 acres the Walt Disney World Resort is the same size as San Francisco, or double the size of Manhattan for you east coast dwellers. Think of Disneyland as charming and Disney World as engulfing.
