Don't know what you (and your girl) like to do, but don't forget to analyze the Shore excursion list on the Carnival website-
At the end of the Cruise, they offered a new Service to take your Bags to the Airport Terminal withouht you having to lug them-we liked that.
You will have the option of Dining in the Dining Room in the back of the Ship in the evenings- if you already haven't, we liked the late seating (you might get back later after a Shore excursion), and we made friends with the people at the Tables all around us-you will be assigned a table, which we liked. If you don't like this option there is many other choices-there will be two formal nights if you eat in the formal Dining Room, so don't forget to take a Suit (and I took a Sports Jacket)-
Have you already booked your Rooms? If you haven't try to get either in the middle of the Ship (less movement), or just below the Verandah deck (close to Food, Drink)-watch out if they book your Room under a Dance Floor, however-
There will be opportunities for Formal Pictures-actually, a ton of pictures-depends on whether you want the memories or not-
If you can (or haven't), I cannot express how much nicer having a Balcony was-you can watch the Ocean go by at Sunset, see things better in Port, and even have a little fun on it (don't ask me how I know)-
Room Service is available 24 Hours, but they will expect a Tip (no charge for the Food)-
All in all it was the best Cruise my Wife and I have ever had-IMHO, Cruises are like going on a date-if you go into them with the attitude that you are gong to enjoy it, you probably will-if you don't, it won't-
