866-227-1888 is where I first learned that “free cruises” are mostly tied to casino offers, loyalty perks, and targeted promos. I called after a friend bragged about getting a free sailing, and I wanted to know if I was missing something. The rep checked my past sailings and told me what I qualified for, plus what kind of onboard play usually triggers those casino offers (way less than I assumed). I didn’t get a fully free cruise that time, but I did get a ridiculously cheap rate just because I asked how it works.
