First, we’re beginning the New Year at Walt Disney World Resort in Magic Kingdom Park with Tomorrowland’s first ever “Bling in the New Year” dance party. For an entire week, children of all ages can celebrate the start of 2013. You’ll be able to watch live entertainment on Rockettower Plaza Stage, dance to great music and celebrate with some of your favorite Disney characters – all dressed in their New Year’s best. And if you can’t stay up until midnight, there will be a New Year’s countdown every hour leading up to midnight. The celebration begins on December 30 and runs through January 5.
