On October 12, 2012, nearly two months before its grand opening, most of the New Fantasyland expansion of the Magic Kingdom was previewed in an unannounced dress rehearsal, including Under the Sea ~ Journey of the Little Mermaid, the dark ride based on The Little Mermaid. This video takes you past Prince Eric's castle, through the elaborate queue featuring interactive animated crabs, and onto the ride featuring binaural audio. Wear headphones during the ride portion for the best experience!
