On our 8/9 cruise the night of the pirate menu we had some pirates come into dinner and do a little song and dance show. Some guests were dressed in theme others were not. We also got bandanas at dinner and chocolate coins on our bed.
I have a shirt with skull and cross bones on it that I was debating wearing as I really didn't know. DH had to go to guest services around first dinner time and he came back telling me he saw plenty of "pirates" roaming around. I wore the shirt...got to dinner and not 1 person in sight had any pirate attire on. I was so embarrassed!

Thank goodness they gave out bandanas so that helped some.
