@styles27 don't worry about @mvh. He/She posts rather mean spirited and prejudiced comments often, and for seemingly little reason other than to make him/her feel better about life. Calling people gluttons and here, accusing someone of not liking Europeans.
I, too, sailed the Mera in December of 2022 on a 4 nighter. I was in YC but did venture out and about a few times and found the same sort of ill-mannered, drunken, entitled fools. I'm talking mid-day sloppy drunk, half dressed, yelling at bartenders for some frozen fruity tooty cocktail and waving their room cards like they were hundred dollar bills.
The crew was doing all they could but it was a mess. I, too, blame it on ridiculously low intro rates including alcohol with no daily limit. As you said, this group made the party crowd on Carnival look like rookies 🙂
