This review is mostly about food, since that was the biggest change over our prior Carnival cruises. I don't know what's happened, but the food and service in the Glory dining rooms was just not good. (This is from someone who has often defended the food on Carnival.) Like some past reviewers, we had a lunch waiter blame the kitchen. We also had the headwaiter explain that they now have 3 people (headwaiter, main waiter, ass't waiter) doing what used to be the job of 4-5. As a result, things were forgotten, including, on the last night, providing some menus! The headwaiter tried very hard, but was busy serving as "waiter" for other tables.
The new menu also seems problematic (besides the food options/quality, discussed further below). It has a section called "starter" (singular). That was confusing as it seemed like they were looking for just one choice there (we made our usual 2 soup and salad/appetizer choices). They had trouble synching the delivery of the starter orders and forgot a starter at most of the dinners, which slowed things down/made things get off track. Also, they didn't bring or ask about coffee/tea at the end, unless you asked them for it.
We also didn't like the new "didja" menu. Not enough good starter or entrE choices. Nobody at our table was very interested in the "comfort" food choices (I got the fried chicken one night and it was just OK). The only really good night was the lobster night (2nd night).
We enjoyed the sushi service and the always-available ice cream and pizza. My husband found the boulibase at the 10th floor fish and chips stand on the last day and really liked it. We also had a seafood salad at the MDR lunch on the last day that was very good (but not very filling, hence the search for the boulibase).
The bar service was mixed. My son had a bad experience with a bartender in the lobby bar, but most of the bartenders were fine. They did do something with the soda cards that took us a while to figure out - when we asked for a Coke, they sometimes asked to see the cards and then ran then through a machine prior to giving us our drinks. We've used soda cards on all of our 20+ cruises and are used to just flashing them, so the first couple of times they did that, we were concerned that they were charging us (they weren't). We think they were verifying that our cards were ours by getting the picture image. Apparently they've had problems with soda card abuse.
Our cabin steward was very good and friendly. Among the best we've ever had.
The entertainment was a mixed bag. The cruise director, Josh, was funny, but not very available except for people he seemed to know well. The comedians (Al Ernst and Macio) were funny. The singers, male dancers, and band were OK, but the female dancers were rarely in synch (maybe they had new additions?). The show I saw, Living in America, I'd seen twice before, but it was fun and within the wheelhouse of the cast. The lounge musicians were also hit and miss - the group we liked best was called Prime Duo (or something like that).
St. John was fine - we'd been there several times before. This time we rented a car and explored the countryside. It isn't the most exciting place, but the people try very hard to be welcoming.
Other things - we usually enjoy the hot tubs, but these were both crowded (lots of kids) and not very hot so we didn't use them. The sea days could use a few more activities - not a lot to do.
Debarkation was easy and quick - we did the self-assist. Our cruise had a high percentage of non-US citizens so we had no wait at all to go through immigration. There was a man working at both embarkation and debarkation who was a gem - he had a great, positive attitude.
Overall, we'd do this cruise again for what it is (a short break before school starts), but hope they work out the kinks with the food and dining room service.
