My personal recommendation is to skip the Pirate Night menu. In my experience, it's the weakest selection.For example on a 7 night cruise it will look something like this:
1: Royal Court, 2: Animators Palate, 3: Enchanted Garden, 4: Pirate Menu, 5: Captain's Gala Menu, 6: Prince & Princess Menu, 7: See Ya Real Soon Menu
Nights 4-7 you continue to rotate restaurants but all 3 are serving the same thing. The same thing is true for anything 4+ nights. So you can plan ahead and determine which menu you are OK with missing when you book your Palo/Remy night.
