For future reference... just spend onboard and charge to your mastercard for 2x points. You get more bang for your buck paying off your cruise charges using points than you do using points to pre-buy on board credit.....
another side hustle... charge say $2,000 to your card at a slot... play once(maybe you win) cash out for the $1999ish. let your MC settle your bill, and that $2000 is worth 4000 points. 4000 points pays off $40 of your MC Statement.
Now say you have a $25,000 limit.... Just saying!!!!
