Walt Disney World hasn’t opened a new theme park in nearly 30 years, and an argument could be made that they really should have.
Over the first 30 years of its existence, the Walt Disney World Resort added theme parks with relative regularity. After the Magic Kingdom opened in 1971, EPCOT Center came along in 1982, the Disney-MGM Studios in 1989, and Animal Kingdom in 1998. However, for the last 27 years, the company has taken another approach. Instead of opening a new park, Disney has instead added to their preexisting parks, for better or worse.
