Sorry you were not impressed, and the music was too loud. If I took a cruise from the United Kingdom for example, I would expect the food to be different than what I am used to. The trivia quizes would most likely be geared to the prominent nationality of the guests on board.
I have sailed on the Glory, and know for a fact that the entertainment staff does not constantly shout on mikes asking if people are having a good time. There are plenty of quiet places to read on the Glory. You just have to look for them. The Library comes to mind, or the outside deck areas away from the Lido.
To each his own about sausage and bacon. I happen to like the American kind, even when cooked by an International Crew.
I agree with macmom and Tom, maybe Carnival just isn't the right cruise line for you. Especially, if leaving from an American Port. As for me, I am looking forward to sailing on Glory again.
