One of the first DISNEYLAND traditions was the nightly fireworks display. In the early days of the park, funds were hard to come by. DISNEYLAND's managers felt that they could save money by eliminating the fireworks since it was believed that park guests weren't necessarily coming to the park just to see them; nor would they stop coming if the fireworks ended.
Walt Disney, however, vetoed the idea. In his mind, the fireworks were a gift from him to his guests. They had chosen to come from around the world to visit his Magic Kingdom and he wanted to send them off with what he called a "Kiss goodnight"- a way of showing his appreciation to his beloved guests. This tradition remains to this very day.
