I have enjoyed Carnival cruises in the past, and they have been a major portion of the 25 or so cruises I have been on, the last Carnival was about 6 years ago on the Dream.
Getting on board was a disaster the elevators forward were mobbed I went to mid ships and they were out of service for luggage so we ended up climbing eight floors to our cabin.
As noted below the cabin was disappointing.
Although I have been on many Carnival cruises, the last time was about 6 years ago, and what a disappointment! They have stripped the cabin clean, no amenities, no Ice bucket, no soaps only the wall dispensers, no stocked refrig. and room service once a day, no more turn down at night, no candy on the pillow.
