I was on the maiden voyage of the Jade. The love/hate relationship comes from Freestyle Dining. Learn how to work with the system and you'll have a good time. Expect more than the system can deliver and you will be disappointed. Eliminate Freestyle Dining and its just like the Carnival Spirit class or the Royal Caribbean Radiance class of ships. The Jade has a water slide and no rock climbing wall, so perhaps it is more like Carnival than Royal Caribbean.
The idea behind Freestyle is eat where you want, when you want, with whom you want. Sounds great on paper, but in actual practice there are a few limitations. Once you understand these limitations you will have a much more enjoyable cruise.
First of all, like land based restaurants, there are busy times and slow times. You can expect that there will be a wait at prime time, just like in land based restaurants. What is important is to figure out when is prime time and when is anti-prime time. I have not cruised in Europe, so I don't know, but I would imagine that since most Europeans eat late, that middle to late is busy and early is not.
Next, not all the restaurants are free (included in the fare). Some have a cover charge. Is the food and service better in the extra cost restaurants over the free restaurants? Yes - would you pay extra for the same level of food and service? As to my experience, the one time I ate in the main dining room on the Star was the worst meal I have had on twelve cruises. The two meals I ate in the main dining rooms on the Jade were fine. The restaurants fall into three categories: 1) Free - no reservations required 2) Free - reservations recommended 3) Extra cost - reservations recommended. Also note, sometimes some of the extra cost restaurants are half price during the slow periods. This will be listed in the Freestyle Daily (the ship's newspaper).
Though I have been on two NCL cruises, I am not sure how early you can make reservations and for which restaurants (you might be able to make reservations one day in a advance, or several days in advance - you might be able to make reservations for the main restaurants or you might not). On the Star (when I was in a normal balcony cabin) I made my reservation the morning of the same day except for the main restaurant when I just showed up five minutes before they opened. On the Jade, when I was in a suite, I made my reservations the afternoon of the same day (being in a suite I knew I would get priority). However, if you read my review you will see that I ate at a free - reservations recommended restaurant and also at an extra cost restaurant without reservations, and my suite status had nothing to do with it (it was just good timing).
Learn to work within the system (as I did) and you will enjoy your cruise. Expect more than the system can deliver and it will take away from your enjoyment. Please note, though I am capable of working the Freestyle Dining to my advantage, I still prefer having a set dinner time. Also, for ANY cruise, attitude is important. Expect to enjoy yourself and have fun and you will. Expect problems and you will.
