Just in Fantasyland and Adventureland?? So it's going to be a small event. Whay can't DLRP do it like WDW and make a big party.
There they have special maps, the CMs are dressed like pirates and the fireworks was the best I have ever seen.
They also have a pirates and princess parade, dance parties and treasure hunts for children and great meet and greet locations where you can take pictures with Disney Princesses and Captain Jack Sparrow of course.
They used the whole Magic Kingdom and all attractions were open, except shows.
If DLRP wants to do a Pirate and Princess Party they should do it in the right way.
