The Second 50th

You could also maybe also add Storybook Land Canal Boats since it was essentially a complete retheming of Canal Boats of the World and didn't open in the modern form until June 1956.

The original Fantasyland train station was also opened in 1956, though it was moved to its current location to make room for "it's a small world."

And then you can end it all by sneaking up to the Fantasyland station for the Skyway, which opened June 23, 1956.

Or you could go all out and drive out to Marceline, Missouri, and walk along the still-present Junior Autopia track that was built when that 1956 attraction closed and Walt donated it to the town.
