Could you say more about what is expected of the children? Are they given lines? Actions? Do the silverware-type background characters just have to stand there? I have an 8yo son who wants to go in his Beast-at-the-ball costume in hopes of getting to be the Beast, a shy 6yo son who will still probably want to be involved in the background only, and 2.5yo daughter who will want to follow them up to the front and do...something.
