Disney on Ice?.. Under 2's?

We are going to see Disney on ice this weekend, My daughter is nearly 4 we have bought her a ticket but i wish i'd of bought one for my Niece she is 3 at the end of January do you think i would get away with saying she is under 2?. I don't think she would want to sit on her own seat anyway i just don't want to get turned away. Has anyone tried this?
