Hi Keisha!
Thanks so much for stopping by the Disney Parks Moms Panel with your question!
What an awesome time your group will have when they visit Walt Disney World Resort for their dance competition. Not only will they get to compete in the state-of-the-art facilities of the
ESPN Wide World of Sports Complex, but they'll also get to enjoy time exploring Walt Disney World's four amazing theme parks:
Magic Kingdom Park,
Epcot,
Disney's Hollywood Studios and
Disney's Animal Kingdom. The Jostens Center, also known as the J Center, is home to many sporting events, including cheer, dance, basketball, volleyball, and more.
From the way you describe your tickets, it sounds as though they are regular 8-Day Park Hopper Tickets, and in addition you'll receive five entries into events held at the Wide World of Sports Complex. To clarify, you may want to check with the event organizers. (Typically Park Hopper Plus tickets will have the word "Plus" written out, and not the "+" sign.)
I hope this helps, and I hope you have an amazing time at your dance event! Have a magical day - Diane W.
