Anthems of the seas 2023

I fully agree I’ve gone on 7 cruises in the last 18 months have used the casino and got a couple of thousand points but not quite reached prime, yet I’ve received nothing except what I won on board maybe a $200 casino voucher, yet I know of 2 people that have cruised once used the casino have not even 1000 points and have received 6 free cruises in the last year, how do they justify that ? Seems like if your booking and paying for your cruises you get nothing although common sense and a good business sense would reward paying customers and especially paying customers that spend money in the casino seems all backwards to me I believe there system is a total and utter load of s***
