Many people have said the ship is two crowded, its more than that, whoever designed the ship never actually followed up on it and had no idea how people behave.
The good, cruising from Manhattan with no airplanes to deal with
The stateroom attendant was wonderful given a thankless job.
The food in the specialty restaurants we ate in (Cagneys, Moderno, Sushi, Le Bistro, La Cucina ) was excellent. Service was good to excellent.
The waterfront is a good idea with bad execution.
The bathroom was the largest of any ship we've been on, nicely done.
The ship caters to smokers. It is horribly designed when it comes to keeping air fresh, in and out. The Casino on deck 7 surrounds a tunnel which allows smoke to permeate decks 7 and 8 the entire length of the common areas.
The waterfront is all smoking, our cabin was amidships and a large amount of the time we could not use our balcony due to smoke rising.
We thought we found a non smoking area near the martini bar which had a smoking section aft and a non smoking section forward. Quite an unpleasant surprise that the staff opened it up to smoking and we had to leave. Complaining to the guest relations about this got us nowhere.
The Manhattan, Savor and Taste restaurants are not good. The service was terrible by our waiter(s) and the food was overcooked. We went for sit down breakfast one day, and the fruit looked as if it was dried out. Sent it back.
The garden buffet is basic, not as nice as other ships. Clearly the better performers were in the paid specialty restaurants.
The jogging track is unusable due to size and crowds (as were the pools),we used deck 8 instead for walking and jogging.
The "minisuite" we paid for was not usable as a suite. Once the daybed was made on the first day, it stayed as a bed and the room was almost impossible for three people to get around in. Should have just got a fold down bed in a regular suite forward or aft to avoid the smokers.
Elevators have a mind of their own and skip floors (this is programming by engineers).
The ship looked nice and had lots of things to select from, but you'd better have 2-3 options considered for activities as you are likely going to be closed out of the first choice.
The little secret was even if the show says sold out, show up anyway, you may get in. Having to pay for entertainment also was bad idea.
Overall- cost a lot of money and than had to spend a lot more for services that are standard on other lines. I would not cruise on this ship again, but based on what friends have said about other Norwegian ships might try.
