On the 9/20 Dream cruise, pirate night and Halloween were combined on the third night. Some folks wore pirate costumes and some wore other costumes. At dinner, we all got the usual red bandana, ate from the pirate menu, and there was a small pirate-themed show. But there was also a Mousequerade party for other costumes and we were told that it was Halloween. So... I guess it was both? The Halloween drinks of the day were on night two, though. It's all very confused at the moment. I don't know why they're doing it like that. Better to split the two themes like they used to do.
Anyway, yeah, no pirate show. There are fireworks and then a short dance party.
