We had a group of 39 people that had saved for a year to go to Jamaica and grand cayman on 1-16-2010. We entered the ship and it went downhill from there. we left almost 4 hours late, ( about 10 minutes till 8 instead of 4:00). The next morning around 7 am. I was having coffee on the rear of the ship and noticed only 1 prop was turning. I thought that was odd and told my wife about it. Well about 8-10 hrs later we received word from the captain that we were having propulsion problems (DUH!) and "tests" would be conducted to see if we could make it to Jamaica, if not we would go straight to grand cayman. Well.... we woke up and found a note in our door stating the tests did not go well and we would not make it to Jamaica or grand cayman but were turning around and going to Nassau! We had several people in our group that had been to Nassau and did not care to return. Oh well! We go where they say we go! We headed directly to the information desk where a crowd was already gathering, I wouldn't be surprised if there was a you-tube video of it. I thought there would be a "mutiny" It was kinda funny actually. But to no avail they would only refund $75 to our sign and sail account for "port fees". Whatever! we were very unhappy with how they handled this whole situation. the information desk said I'm sorry there's nothing we can do and that's it! We got the same answer from the corporate office over the phone. We also emailed corporate. All in all CARNIVAL was unprofessional and rude. And to think that there were 2 wedding parties on board that had families meeting them in Jamaica that were now not able to get married!! And I thought we had it bad! AVOID CARNIVAL!!! They are not customer friendly!
