Where to begin?
-The dragon. DL uses a full audio animatronic dragon that breathes fire. WDW uses a dragon head attached to PVC pipe with some black drapes dangling off of it.
-DL has a Little Mermaid sequence featuring Ursula, and giant Flotsam and Jetsom characters. The way Flotsam and Jetsom menacingly lurk around the water is eerily real.
-The Peter Pan sequence is vastly superior to the dull Pocahontas segment.
-The Steamboat Willie boat at the end of the WDW show looks like a cheap reproduction when compared to the Sailing Ship Columbia that DL employs.
Also, I'm no DL partisan as anyone who knows me will attest. However, on this particular issue, there is simply no argument. The DL version of the show is vastly superior to WDW.
