Finding out exactly which night is "Pirate Night" is a top priority for families wanting to pack their costumes. The most reliable way to confirm the date is through the Disney Cruise Line Navigator App once you are linked to your reservation. Usually, about 30 days before sailing, the app will populate with a daily schedule, and Pirate Night will be clearly marked with a themed icon. If you want to know even earlier to plan your packing, you can check the "My Plans" section on the Disney Cruise Line website; while it might not give the specific hour, it usually lists the theme for each night's dinner. For most Caribbean and Bahamian sailings, Pirate Night typically occurs on the night the ship visits Nassau or is at sea, but rarely on the final night of the cruise. You can also look at your "Rotational Dining" schedule; the menu in the main dining rooms will change to a pirate-themed menu on that specific evening. If all else fails, a quick call to Disney Cruise Line or checking fan forums for your specific itinerary and ship will usually provide the answer.
