No. K is holding firm that she can't go. :-( I plan to buy the 3D version on DVD when it comes out in December and watch it at home. I'm 99% sure she would keep the glasses on because she wears her sunglasses all the time with no issue. And she loves nemo that much. I think she'd just be a statue watching the whole things in amazement.
Wait? Your theater is showing it in 2D as well? I wish ours was. :-(
