I see it quite differently. I bet next year there will be warnings sent out to all other passengers.
You should not have to explain to your children they can't swim because the drunk skanks are watching the drunk fatboys do belly flops in the pool where running and diving are normally strictly prohibited. On a cruise ship you can't escape them and you can't enforce rules with a group that large. It can be pretty scary for some. Ugly drunks acting like themselves is just ugly.
Had they taken a SUV ride to the black hills and Sturgis during bike week I would have a different outlook on it.
