For some it was just another summer day at Disneyland, for others, July 17 was a day to celebrate.
The date marks the 70th anniversary of Walt Disney opening the Happiest Place on Earth.

The first people to visit the park on Sunday, July 17, 1955, were invited guests during an “International Press Preview” event that included studio employees, construction workers, the media and company sponsors.
The park actually opened to the public the next day: July 18, 1955.
For Thursday’s anniversary, the crowd that gathered at the main gate was greeted with a train full of Disney characters that pulled into the Main Street Station just before the park opened.
Visitors were handed a commemorative pin and special edition guide map as they entered and were welcomed by cheering employees lining Main Street, U.S.A.
The afternoon had a modified parade, “The Celebrate Happy Cavalcade — Disneyland’s Birthday Celebration Edition.”
But most of the park was business as usual, with park visitors enjoying what Walt built.
