I have sailed on Carnival three times now. The Dream last December was awesome.
This boat not so much. First off, it stank of sewer the whole time I was on it. Some location of the boat the smell was more intense. The entire boat just needs a good washing job.
The bartenders are rude as hell. The wait staff was better but it seems as thought the least seniority crew runs this boat. The drinks are so watered down that I just started ordering martini's all day long and then still seemed to be watered down.
