No Event Too Small: Disney World Opening Day Crowd Control (Disney Dispatch):

Then we hit upon another scheme.

Our laborers had been working 12-hour shifts, without much time off, and that ran us afoul of labor laws. So we decided to pick a weekend and have the laborers come into the park not to work but to enjoy the day with their families.

Dads proudly showed their kids around the park, explaining that they were the ones building it, but at that time there were only 3-4 rides running, and so the kids would say: "well, hurry up and finish."

(Great motivation! The next day, when work resumed, it seemed to go a lot faster.)
