If you run $12,000 through the slots either with your money or money won you will get free cruise offers or very discounted offers with on board credit or casino credit. Going on the Mardi Gras for new years and was given an Excel Suite at a discount and $1,000 on board credit. On RCCL my last cruises in 2018 and 2019 I was given a Owners Suite and added my Son as a third guest for less than an inside cabin. Could I have just booked my Suites at regular rate and not gambled? Yes.
