The Animation Studio is one of my favorite places in DCA.
Through the end of April, they are having a special tribute to Snow White in the main area. Besides Turtle Talk, there is the Toy Story Zeotrope which Albort mentioned above. Really, really cool! Beast's Library where you find out which Disney character you are most like, and Ursula's Lair where you get to sing to Disney songs while Ursula captures your voice!
Drawn to the Animation program where you learn to draw a disney character may be a bit advanced for a 3 year old, but older kids and adults usually love it.
