Yes - it was open last week when we were there - but it is a waste of time and I skinned my knees on that rough white (snow) carpet they ask you to sit on!! Just a promo of the movie and then some props from the movie - nothing special.
Actually, I'm jealous, Tiggerfan, we were so packed in, no one could sit. And the first cast member had an extremely strong accent. To the point of being unintelligible at times. I realize that he is a probably a very good worker, but someone should have listened to him read the script before they put him out in public. It's not fair to him!
One good thing about it - the lady playing the White Witch was very, very good!
Just to clarify my statement above; we were there in January doing a site visit of the animation studio and narnia exhibit for our wedding reception next January. We were told that it would be there for our date, so since we are still considering it, I hope it's not just there for 3 or 4 months
