I'm not defending that behavior on Carnival but even
DCL can have bad behavior. There is a video going viral on Tiktok of an adult woman trying to slide down a banister on the Wish and then falling to the side and hanging on while her friend goes to help her.
The thing that helps DCL not often have violent issues is a lack of a drink package. But while I was on the Wish in May there was a group of drunk passengers on the second floor of Luna who kept disrupting Match your Mate and then when asked to behave by the CM were yelling back and hanging over the balcony (far over) and it went back and forth for way too long before security actually did something. Bad behavior is not just a Carnival issue.
