One of my favorite things to do on a Disney cruise is pirate night. It’s so fun to put together a pirate costume and wear it up on deck for a big party which ends with fireworks out over the ocean. There are a lot of good tutorials online for easy and cheap DIY pirate costumes. Ours is basically just a plain white T-shirt that we have cut jagged edges along the bottom, red solid material cut into strips for our belt/sach, eye patches from the dollar store and whatever type of shoes and pants you might already have around the house that would finish off the look.
