Having just got off the sister ship Celebration, I have to say that most of your comments are spot on for us as well. I don't believe I will ever cruise that size of a Carnival ship again. Prices remain the same, but ships are totally understaffed.
Having just been at Amber Cove and Grand Turk five years ago, I was looking forward to those stops again. I was sorely disappointed. Jack's Shack was nothing like it used to be, and you'll go broke sitting there and paying the current prices. Magaritaville was nothing like a laid back Caribbean atmosphere, but a ghetto nightclub at 3:00 in the morning. What a letdown at Amber Cove when the main entertainment at the pool that day was a twerking contest.
