Our Carnival Destiny Cruise in February 2008 was great. We definitely got a good value for the price, so I feel hesitant to provide some of the feedback since I attribute my experience to what the trip costs.
For a cruise that was less than $90 per person per day for an inside cabin; The shows were entertaining, the accommodations comfortable, and the food fulfilling. If this cruise would have been the average going rate, then I would have considered the shows dated, the accommodations a bit worn, and the food average in both presentation and selection.
I found the activities schedule to be a bit light and very heavy into the late evening. Their were very limited activities while ship was in port. If you are seeking a R&R vacation, then this floating hotel would be just right for you as it empties out at every port. You would have choice of lounge chairs.
