I got the same thing for the June 23 Rome-Barcelona itinerary. I was surprised too. I had the Freezing the Night Away party on my UK/Iceland/Norway cruise in 2016, but there was no Pirate Night on that one. It seems odd that they'd do both. My cruise is only 7 nights. Would they have deck parties for 2 of the 7? (3 of the 7 if you count Sail Away)
They don't. It was copy and pasted from their general summer press release.
