"Bit by bit, Disneyland got ready for Opening Day. The staff worked around the clock to get ready. The Mark Twain was being moved, deck by deck, down the Santa Ana freeway to get to Disneyland on time. Finally, everything seemed to come together. The "magical little park" was really a $17,000,000 "Magic Kingdom." Walt's dream had come true and Disneyland was ready to open."
Opening day, was a day to remember. Six thousand invitations to the Grand Opening had been mailed. By mid-afternoon over 28,000 ticket holders were storming the Magic Kingdom. Most of the tickets were counterfeit.
Walt Disney was 53 when he dedicated Disneyland Park. It was a memorable ceremony. There in Town Square, Walt could look around and see the fulfillment of his hopes, dreams, and ambitions in the form of a spectacular entertainment kingdom."
