I heard a story about how when Kruschev came to the US (same trip at "We will bury you") he wanted to go to Disneyland, but that Walt refused to allow a Communist into his park no matter how much the State Dept tried to cajole/threaten him. I've researched to verify it, but haven't found anything else. Has anyone else heard that story?
I Googled Kruschev visit Disneyland.
Looks like security is the only common thread that makes sense for denying Kruschev access.
“Furthermore, Disneyland became a cultural icon. Even world leaders like Henry Kissinger were drawn to the place. Legend has it that during Kruschev's visit to the United States, his major disappointment was being denied from visiting the park. (The Secret Service were concerned that they couldn't guarantee his safety.)”

“Walt Disney was proud of this attraction; he intended to show "the world's seventh largest navy" to Russian Premeir Nikita Krushchev during a trip to Disneyland. The Secret Service was afraid they could not provide enough security in the park, so the visit was cancelled, angering Kruschev and disappointing Walt.”
