In just a little more than a month, Rapunzel will be welcomed into the Disney Princess royal court, and Disney.com is giving away a trip for four to the official celebration at Kensington Palace in London on Oct. 2. Fans ages 12 and younger can enter the My Princess Moment The Story Begins With You video contest through Sept. 12. Videos should have the contestant recreating a favorite Disney Princess scene, dressing up or performing a dance. To get started, choose a song clip online from Disney Princess Fairy Tale Songs, which will be released Sept. 20. No other music can be used. Videos also will be accepted through Oct. 4 for one first prize, which is a 3D TV and DVD collection from Walt Disney Studios Home Entertainment, and 10 second prizes of the Disney Princess Ultimate Dream Castle. A panel of judges will score the videos on entertainment value, creativity, personality and style. To enter and for complete rules, see Disney.com/PrincessMoment.
