My wife and I have sailed Carnival before about five times. I will skip over what anyone who has sailed carnival already knows and get into the specifics of this trip and ship.
The Carnival Breeze is an almost new ship. A few differences between the Breeze and other Carnival ships are the following: the entertainment was typical Carnival stuff. Not Broadway but more like a small regional production. If you expect the Broadway cast from Wicked, it "ain't" going to happen. It was something pleasant to spend some time after dinner. The theater itself is rather small vis-a-vis the number of ship's passengers so do not tarry after dinner if you have your heart on seeing one of the shows.
The food was typical Carnival too. The maitre d' Yogi was way above the norm and was very "hands on". You usually see Carnival maitre d' s only on the last night with their hands out expecting a tip. The serving staff was excellent although there were more changes that the norm in the course of the cruise.
Carnival has upgraded its TV infrastructure so the programming is better than a couple of years ago and you can check you ship's card balance at any time. The Tour Director Jaime was one of the best and a very tall, thin willowy blond was uncharitably (but correctly) named 6'3". I thought that this was dehumanizing but who philosophizes on a cruise? The captain spoke incomprehensible English that Jaime "translated" into intelligible English. There was no gym per se and Carnival has increased the number of "non-free" activities. They really push their salon for treatments and product. To me it's all grease and snake oil but some people like it. The room stewards were good and the ship always looked clean.
On a scale of 10 (great) to 1 (poor) I will rate the shore excursions with an occasional comment.
1. Monaco-Monte Carlo...n/c too windy; did not dock; this was for us the least important port so we didn't cry over missing it. The port has a "poor kids with their noses pressed against the bakery window drooling over sweets they cannot afford" quality to it.
2. Livorno...5...bad weather hampered tour; two hours in Florence and one in Pisa. uninspired bu good if you "must see" the Leaning Tower before you die.
3. Civitavecchia/Rome...3...my wife went to Rome but I opted out because I had been there several times before. I went to Tarquinia (see other cruise reviews) which was a great alternative. Wife had such a terrible tour of Rome that they refunded 20%. Tarquinia shuts down tighter than a drum from 12:45 pm to 4 pm for the siesta.
4. Naples...8...most reviews advise not going to Naples proper so we followed that advice; went to Mt Vesuvius (rather strenuous climb, not for someone with physical disabilities) and Pompeii. Spectacular views of Bay of Naples from Mt Vesuvius. Pompeii jammed pack with tourists.
5. Venice...9...wonderful, surreal port; tricky to get off the ship to Piazza San Marco; transportation relatively expensive, even public vaporetti; absolutely loaded with tourists; Alilaguna water taxi (located on the peer itself) is the best deal from peer to Piazza San Marco.
6. Dubrovnik...8...quite spectacular "old world" look and feel; economy almost 100% dominated by tourist trade. Lots of shops and restaurants; geographically small (150 square acres) so you can "do" the city in a day; must have been an unspoiled beauty in the mid-90s. They have not yet been admitted to the Eurozone (a dubious honor) so the merchants are rather eclectic in terms of currency use.
7. Sicily...8...took shore excursion "In the Steps of the Godfather"; visited two towns that figured prominently in the movie; kind of a long bus ride to get to the first town Sabocca. As the reviews state, not much to do in Messina where the peer is located.
Generally the Breeze enforced the "do not bring alcohol" aboard rule rather loosely.
