Not sure if you guys have seen this yet promotion yet, but i uploaded a picture of a $50 freeplay offer from Choctaw and I got a free-ish cruise on Royal Caribbean. Just had to pay taxes

The cruises they're offering right now are pretty last minute but I've had a few other friends say they got cruises from norwegian for next year too. Guess it depends on the size of the offer you upload
