When we were at DL for the 50th, they did a dedication ceremony every day by the Train station. They played the speech that Walt made and it was very moving. Do they still do it?
I know that near the end of the 50th they moved it to in front of the castle, and made a few changes to it. I believe it was just part of the 50th celebration and it as ended. But, it would be worth asking about when you are there.
