Disneyland is celebrating 70 years of being "The Happiest Place on Earth." The summerlong festivities in southern California include the opening of "Walt Disney – A Magical Life," a show featuring a lifelike animatronic of the company's founder that debuts Thursday and also marks Disneyland's official anniversary.

And we're excited for the new experiences that our guests are going to get to experience," said Disneyland Ambassador Raul Aquino Rojas. To start the 70th anniversary celebration, Disneyland sent San Francisco the biggest invitation ever - a 75-foot-tall hot air balloon.
