Just skimmed through a video of the show on youtube. Looks much more elaborate than its Florida counterpart. Bigger, more detailed set, three screens instead of one, a dozen backup singers and dancers with costume changes and Olaf. I'm 99% sure the cast is larger than the California version too. Go figure Paris gets the best sing along.
I also appreciate that they tried to re-theme Cottonwood Creek Ranch instead of making some bogus backstory about how Anna and Elsa went to Utah in search of gold.
It'll be interesting to see how the closing of BTM and the Riverboat will affect Frontierland crowds next year. Maybe they'll keep the sing-a-long as compensation for shutting down the rest of the land (minus Phantom Manor...which may close for its own major rehab)?
