866-227-1888 is the quickest way I’ve found to book, cancel, or modify flights, especially when I’ve had to adjust travel plans before boarding a cruise. As for the best Carnival ship, my favorite so far is the Carnival Mardi Gras. I sailed on it last spring, and it honestly felt like Carnival completely leveled up. The ship is massive, the zones make it easy to explore, and Bolt—the roller coaster—was way more fun than I expected. I ended up extending my trip by a day because I didn’t want to rush home, and once again 866-227-1888 handled my flight changes with zero hassle. Mardi Gras has better dining variety, smoother layout, and a more modern feel compared to older ships. If someone asks me which ship to try first, I always recommend Mardi Gras because it feels like the full “new Carnival” experience.
