Special Voyages Cruise

We're cruising to Bermuda June 30th..its a 7 day cruise. I keep getting those "your FUN cruise needs your attention" emails and when I read it, it says the message below. What does a "Special Voyage Cruise" mean? I didn't see anything about that when I booked it.

7 DAY SPECIAL VOYAGES CRUISE

CARNIVAL PRIDE

it might be because you are cruising during July 4 which is a holiday. holiday cruises might be special.There is some decorations on the ship during that day and a theme cake at the buffet on that day

Thank you for the response..I never would have thought of that.

Also Carnival in any given year only sails to Bermuda maybe 7 or 8 times from 3 departure ports.
