Correction: Disney World is less a "city" and more a suburban sprawl nightmare development you'd typically find on the outskirts of Vegas. It was poorly planned from a land-use perspective. They had so much space to work with that they chose the easiest and cheapest building locations for their parks and resorts and now there's no turning back. Disney World = Orange County (Poorly planned, spread out, limited transportation options, lack of reasonable pedestrian options, and a complete lack of density which results in long travel times, wasted energy consumption, and wasted time spent in-transit TO your destination instead of enjoying the time AT your destination.
