Not yet. It has been practiced with show stops, but they weren't sure they were going to use them. Today's preview did not have show stops and it was just fine without them.
The other thing that is missing . . . . The ENDING! There was no finish to this parade today. The big ending float from the parade concept was never constructed. Then they were going to use a Cars unit. But for some reason, they didn't use that full unit today . . .
Still, the parade is a lot better than the Block Party Bash and much more Disneyland-like in its scale and quality.
This was just a first preview, I'm sure they'll work the bugs out of it and figure out an ending.
