I often hear “Only Disney.” Only Disney can create such a fun attraction…only Disney can throw such a big celebration…only Disney. Well, it all started with the man himself. When he opened an attraction, he went all out. In true Disney style he made the opening itself a show worth watching. Go back in time in this video montage of some of Walt’s “opening days,” starting with the biggest opening day of all — July 17, 1955. That’s when more than 28,000 guests showed up for the opening of Disneyland park and the American vacation changed forever. This video also includes the opening of Matterhorn Bobsleds (1959), New Orleans Square (1966) — Walt’s last official ceremonies before his death in December that year –- and Pirates of the Caribbean, the last attraction that Walt supervised. Unfortunately, he passed away shortly before Pirates’ opening day.
