Hi Jane and welcome to the Disney Parks Moms Panel.
I have just checked the hours for the
#INCREDIBLESSuperDanceParty at the Magic Kingdom Park on the Walt Disney World website and can confirm that at this moment in time, the hours are only available to view for dates up to and including September 10, 2016.
I would recommend that you keep checking the Walt Disney World website frequently between now and the date of your arrival to see if the hours have been added for dates after September 10, 2016.
Alternatively, be sure to pick up a Times Guide when you check-in at your Disney Resort hotel or upon your arrival at the
Magic Kingdom Park to see if the dance party will be taking place on the actual day of your visit.
Wishing you a magical trip filled with memories which will last a lifetime!
Emma
