The things that people wave (streamer type things) are given out, if that is what you are talking about. On my cruise in October, they didn't give any out. It's a good time!!
I'm not sure what you are asking about the steps. Maybe someone can help...
As far as characters, it depends what sailing you take (more on 7 nights) but usually they have the princesses, Mickey/Minnie, Donald, Daisy, Chip and Dale, Goofy, Jack sparrow, Lilo and Stitch and a few others.
