Hi Kristin,
Congratulations! I absolutely love hearing about guests first visits and thinking about all of the Pixie Dust that awaits you on your magical vacation. Your family will create so many memories you will cherish forever. Yipee!
The
Disney Junior Dance Party is an event held only during Evening Extra Magic Hours at Disney's Hollywood Studios. It appears Disney's Hollywood Studios is scheduled to have Extra Magic Hours on the night of June 9, 2014, so I would expect the dance party to be held then, starting around 10 PM. (Please be aware these schedules and events are subject to change at anytime.) The online calendar should reflect times soon, but also make sure to grab a times guide when you arrive at the park. My kids really love this fun and interactive event, so we make sure to plan an easy day beforehand and account for plenty of time to rest and relax prior to them dancing the night away. We have taken some incredible pictures at this event, while they danced with so many of their favorite Disney Junior friends.
I hope you are able to include the dance party in your vacation plans. I am sure your kids will love it. If there is anything else I can assist your with while planning your inaugural visit, please don't hesitate to ask. I love sharing fun ideas and answering questions for our guests.
Have a wonderful vacation. I hope it is just the beginning in creating many more magical Disney memories.
Enjoy,
Lauren
