I sure would love to see were all these parties are on carnival as after 3 cruises with them I have yet to witness such acts. I don't consider people participating in onboard activities as a party to me it's having fun.
It's too bad they cant seem to looses the title of party ship.
As far as dressing for dinner I don't get how it would make someone uncomfortable if other are not dresses to you liking.
People have way too much time on their hand if you are bothered by such silly stuff.
