On October 23, 2003, Dubailand was announced. It will cover 278 km2 (107 sq mi) and will feature 45 “megaprojects” and 200 subprojects. There are 22 projects presently under development. Attractions and Experience World, Sports and Outdoor World, Eco-Tourism World, Themed Leisure and Vacation World, Retail and Entertainment World, and Downtown are the six zones (worlds) that comprise Dubailand. It will be double the size of Walt Disney World Resort and will house the world’s biggest collection of theme parks; nevertheless, no theme park in Dubailand will be larger than Disney’s Animal Kingdom (located at Walt Disney World Resort).
