Disney really wants us to be super excited about the holidays. Almost every post from their various news sites is all "Holidays! Sparkle! Fun!" or something of that ilk. Hollywood Studios was the first to get the holiday makeover, likely to try and bring in foot traffic early.
The decorations are absolutely worth seeing, no matter what. The 1940s-style decorations fit right in with the aesthetics of the park. I'm happy to see that they are going all out for this park, especially since we no longer have the Osborne Family Lights Show. I can't wait to see these decorations in person — I promise I'll get a ton of pics!
