Many portions of the park weren't ready. Attractions broke down. The asphalt was still drying on Main Street. Women's high heels were sinking into the asphalt. Also, there was a plumbers' strike, and Walt had the choice of having either working restrooms or working drinking fountains. He chose the restrooms, of course.
What we really do is tell entertaining and compelling stories, through our rides, shops, restaurants, entertainment, even our resort hotels.
It was very much a gamble. Everyone told him it would not work.
