I'm hoping we take a few things from DCA next year, the Carsland specific decorations are beautiful and could jazz up that section of Toon Studio well! Maybe a Crush equivilent could be made - a Christmas tree made of coral? Jellyfish string lights?
The Buena Vista Street theme is beautiful too, tasteful and festive without being in your face, that could easily be added to the Partners and Hollywood Blvd area!
Backlot could have a tree made of amps/lighting rigs, you could even add Santa to the Tram Tour! Call it the Jingle Bell Tram Tour or something, and have him sitting in a sleigh, in the woodland area to distract from the Ratatouille construction walls!
A lot could be done, and I sort of hope that now it feels like there's this whole new improvement mentality filtering down from WDC we could start to see changes along the same lines as DLP got!
