This sounds like it's been updated since I saw it last year. The wardrobe and forest were the same, as was the room with the props. But when we saw it, there was just a movie screen in the forest that showed what was basically an extended trailer for the movie. I'm glad to see they've updated it because it was really very disappointing. The forest setting was amazing, but to be in that gorgeous setting and see a 10-minute compilation of movie clips was a real let down. We will have to check it out again in 2 weeks - I'm so glad I opened this thread!
OP -- if your DD loves Narnia, I'm sure she will love this attraction. It's very cool to see the actual props and costumes that were used in the movie. My only gripe last time with this part was that they kind of hurried you through that section before the next group of people got done with the movie. I hope they've changed that too, because I like to linger and admire all that neat stuff!
