Hi Roxana!
Thank you for visiting the Disney Parks Moms Panel. I have cousins who do not speak English who have visited the Walt Disney World Resort and loved every minute of it! They brought their children and to still see the excitement and magic in their eyes when they see their favorite Disney character or recognize something they have only seen on TV is priceless. Disney has a way of telling stories that reach many languages without the need to translate.
That being said, Walt Disney World does offer
Ears to the World, Disney Show Translators. These are wireless headphone units Guests can wear during select attractions. Each translation is synchronized with the attraction, providing a truly magical experience from start to finish. Disney Show Translators are complimentary and available at Guest Relations in each of the 4 theme parks. A refundable $25 deposit is required. Jedi Academy or Jack Sparrow's Pirate Tutorial is currently not on the list of shows available for Disney Show Translators. You can find the list
here.
If your children are huge fans of Star Wars or of Jack Sparrow and Pirates of the Caribbean, then I would say go for it! If your children do not speak any English, then it could be a safety concern if they wish to participate in the show. You can take them to watch either outdoor show and may certainly leave at any time if they are not enjoying themselves. I would also suggest watching YouTube videos to help you decide whether it would be something your children would enjoy.
All 5 of my daughters have fallen in love with Walt Disney World before they could even speak! It truly is the Most Magical Place on Earth!
Buena suerte and have a magical vacation!
