TERRIBLE!!!!

I chose this cruise for its itinerary which was supposed to be Cozumel, mahogany bay, Belize and cayman island. However, the day before the trip we received an email that the propeller wasn't working at maximal speed and that there was a change of itinerary and the ship was now only going to the Bahamas (Nassau and Freeport- which is a FREE port at no cost to the ship) we had already flown to Miami so we agreed to make the best of it and go on the cruise. However it was an AWFUL trip. We went from going to 4 ports to only 2 ports on a 7 day cruise. Many members were asking to go to one extra port but carnival wouldn't allow it. We were stuck at sea for most of the trip. This ship is SO outdated. The decorations are ridiculous and terrible to look at everyday. The safe box in our room broke and it had our excursion tickets in it. I had almost missed the excursion because we had to call the service desk 3 times to open the safe. The only good thing about this ship was the food and servers were great- very friendly and welcoming. However, during the day at sea, the workers were washing down the chairs at 11am while people were trying to relax for the day. So RUDE!!!! At the end of the trip we were billed $97 PER PERSON for "tips". When questioned, the service desk was so rude and asked "I don't know why you're so surprised, it was written on a paper you signed" well maybe it was but I had been tipping people every day and then we get billed the LAST day for all the tips? This should be taken out at the beginning of the trip. Plus, were tipping the "behind the scenes workers? For what? Doing their JOB? I wish I got tipped everyday being a nurse for just DOING MY JOB! We were supposed to get half of our money back for this trip but we only got 1/3 back. I have never been so disappointed on a trip. If I could turn around time I would have cancelled this trip. My extended family were in the process of planning another cruise later in the year but I can NOT recommend this line. I recommend booking a trip with another cruise line- NOT CARNIVAL!!!!!! Awful awful experience
