It's strange when people complain about move it shake it, or other cheap dance parties and others say "what's wrong with families dancing and having fun in a theme park?"
No one is saying families shouldn't dance and have fun in a theme park. But many of us know that Disney is capable of giving them fully produced, theme appropriate entertainment to dance to. This is a problem unique to florida. When you visit California you see live music around every corner. They even have a big band host a "royal ball" dance party on the weekends!
Look up videos of Festival Navi Dav or Mulans Lunar New Year Festival at DCA. That's what I expect from Disney.
