Pirate night is Monday, Nov. 30th. That will be on the same day as we dock in Nassau.
A helpful tip: If you go to the area that you need to for your online check in, you will notice several other tabs that can be clicked. When you get a chance, click through them and take a look at all of the helpful information that Disney has compiled for you. They have a place to schedule a character call (which is free....I still like doing this even though our boys are 19, and 15), book excursions and on board experiences like Palo or the spa, precheck in your kiddos for the kids area, and a daily planner. This is where you will be able to see when the pirate party is scheduled for. If you have not booked any excursions yet, you should have 2 items scheduled in the daily planner. That will be the sail away party on Nov. 27th, and the Pirate Party on Nov. 30th.
I hope this helps. If you have any other questions or things you may have missed, feel free to ask.
