We have sailed with Carnival before and have been happy enough, but this is the first Carnival ship I would actually go out of my way to book again! There is no excuse to be bored on this ship, no matter what your age. We spent a great deal of time in the Lido Pool.
The interior decor in the Breeze is noticeably different from other Carnival ships, and in a good way. Tasteful colors and patterns make it different from the clown-inspired designs of Carnival ships past. I used the early saver program to upgrade my interior cabin to a cove balcony, and I am spoiled now! The cove balcony is a lower balcony on level 2, very close to the water, and shaded by the lifeboats above, so you aren't blasted by the sun like on a regular balcony.
We mostly ate in the buffet, as dining rooms on cruise ships are notoriously slow, and we don't like to dress up just for a meal. We do like the more casual dress code Carnival has now, and spent a couple of nights in the Blush.
