I agree 100% with the OP. I consider the casino part of my on board entertainment.
On our last Princes cruise there was three line 7/5 Bonus Poker for 10 cents. It was so fun to play and we broke about even. On our last X cruise, it actually felt like there were bad chips in the Video poker machines. I know they are not regulated but really no winners, in 14 days the two of us playing here and there every day, we only had five four of a kinds. No one was playing the long line of video poker machines. If video pokers rates are bad, the slots are always worse in same casino in my experience.
