I saw it past October. I had some apprehension because it was a non-equity tour, but I was finally really satisfied. As far as I can tell (from the promotional material), the set and the costume are identical to the equity tour. The lead cast are good. They cast actors who sound a little like Laura Osnes and Santino Fontana. Leslie Jackson, who played Maria (godmother) really stole the show, even though she is quite young for the role. Her version of «There is music in you» is amazing (Here is a link of her singing in Ragtime non-equity tour: https://www.youtube.com/watch?v=L9zvVUrO560).
I saw the production in the beginning, so I guess the production might have improved. The actress who played Cinderella was not the best dancer. And most of the joke said by the stepmother sound flat. Most of them didn’t receive laugh at all. Nevertheless, my sister and I have a great night.
Maybe I do not speak English as well as you, but I can perfectly pronounce the names of all characters of Les Misérables.
