Carnival Imagination is a tired ship that shows its age. There is nothing particularly outstanding about this ship, and much of the decor is quite garish. The main atrium is neon from top to bottom and the dining room is also appointed with strings of neon lighting. We felt the economy nature of this cruise in the service--very slow in the dining rooms, no extra assistance by other crew members. While on other cruise lines the staff go beyond the call of duty to make passsengers happy, on this ship there's little effort beyond the basics. We were surprised that the very impressive entertainers did the exact same show on the first and last nights of the cruise! The second show was also very similar in style and content as well. The water park is old and not particularly impressive, especially when matched against Disney or other more modern ships.
We had an ocean view cabin for 5 (two adults and three kids). The beds and bedding were comfortable. With all clothes unpacked and stored on shelves/in closets and luggage stored, there was some room to maneuver. Bathrooms are basic, but the shower curtain was rather disgusting--especially at the bottom. The plug in the bathroom was above the sink facing down, and did not hold the connection making charing of devices difficult. Cabin windows were very dirty and in need of being washed. It was actually difficult to see through the windows because of built up grime.
Various details of the ship are really in need of updating...we noticed burnt out light fixtures, shabby paint jobs, and the windows of our cabin were so dirty and in need of being washed that it was hard to see out of them. It's hard to beat the value of a Carnival Cruise, but know that a lot of corners are cut in the process. Definitely buy the Fast Pass to Fun--totally worth the expedited boarding and disembarkation.
