Hi Angel,
I think that you are talking about the
Star Wars Weekends which are held annually at Disney's Hollywood Studios theme park.
Star Wars Weekends celebrate the legendary Star Wars Saga and the animated television series, Star Wars: The Clone Wars. On Friday, Saturday and Sunday of each weekend, you can join celebrities and characters for special shows, panels, presentations and more!
Historically, they have taken place on the last two weekends of May and the first two weekends of June and based on previous years, I would expect the dates for the 2012 Star Wars Weekends to be released in January or February 2012.
My family hope to experience this special event for the very first time next year also.
Wishing you a magical trip and may the force be with you!
