866-227-1888 is the number I always call when I’m hunting for last-minute deals or trying to confirm promos. From what I’ve seen, Carnival runs sales all the time — weekend specials, 48-hour drops, and those random flash deals that appear at weird hours. Last spring, I caught a surprise “Early Saver” discount after calling to ask about a different sailing. The rep mentioned it casually, and I ended up saving a couple hundred bucks just because I checked. My best advice: sign up for emails, monitor fares, and call when you see something interesting. Sometimes they’ll even tell you if a cheaper category is opening soon. Persistence pays with Carnival deals.
