Norwegian Prima’s deck plan has a quirk that most booking engines will not show you. The ship carries 1,646 cabins across 35 categories, and the size difference between the smallest and largest standard balcony cabin is over 120 sq ft. Two passengers can book the same category, pay the same fare, and end up in rooms that feel completely different. The cabin number matters as much as the category on this ship.

I sailed Norwegian Prima on a transatlantic repositioning from Europe to the United States in 2025. I booked a midship ocean view cabin and paid no single supplement at all. That booking taught me a lot about where the quiet spots are on this ship and where the noise creeps in.

How This Ship’s Layout Works

Norwegian Prima has passenger cabins on Decks 5 and 9 through 16. Deck 5 sits low and houses ocean view and inside cabins only. Decks 9 through 16 carry the bulk of the accommodation, including all balcony cabins, suites, and The Haven complex.

Public spaces cluster on three levels. The Prima Theatre and Club occupies Deck 8 forward. The Indulge Food Hall and Ocean Boulevard wrap around Deck 8 aft. The pool deck, Surfside Cafe, and Speedway racetrack sit on Decks 17 through 20. The Haven’s private areas - restaurant, bar, lounge, and infinity pool - are on Decks 16 and 17 aft.

The engine room sits below Deck 5. The ship uses azipod propulsion, which means less vibration than older shaft-driven NCL ships like Norwegian Star or Norwegian Epic. That said, the lowest aft cabins on Deck 5 can still feel the thrusters during port manoeuvres.

Best Balcony Cabins

The standard balcony cabins on Norwegian Prima are larger than those on most other NCL ships. They start at 231 sq ft with a 45 sq ft balcony. The floor-to-ceiling glass doors make a real difference compared to older vessels.

Deck 11 midship, port or starboard, categories BA and BB, is the best zone. Cabins 11100 through 11170 (port) and 11700 through 11770 (starboard) sit in a pure residential stretch with no public spaces above or below. You are three decks above the theatre and six decks below the pool. The motion is minimal here on sea days.

For a premium pick, the aft-facing balcony cabins on Deck 9 (category B1) deserve attention. These run around 268 sq ft inside with a 102 sq ft balcony - more than double the standard balcony size. The wake view is superb, and the larger outdoor space makes them feel closer to a junior suite than a standard cabin. They are priced higher than midship balconies, but the upgrade is meaningful.

If you want a quieter experience with a perk, the B9 Thermal Spa balcony cabins on Deck 16 include complimentary access to the Mandara Spa thermal suite. At 231 sq ft with a 45 sq ft balcony, the cabin itself is standard, but the spa access alone is worth around GBP 200 ($250) for a week-long sailing.

The trade-off with Deck 16 is proximity to The Haven above and the Speedway racetrack further up. The go-kart noise can carry down to Decks 15 and 16, particularly on midship balconies with doors open.

Best Inside Cabins

Inside cabins on Norwegian Prima range from 160 to 254 sq ft. That is a huge spread. The larger insides are on Deck 5, where the hull curvature creates a few oversized cabins in the I4 family category. If you can find an I4 on Deck 5 midship, you are getting a 254 sq ft inside cabin - larger than some balcony cabins on older ships.

On the upper decks, the standard IA category cabins on Decks 12 through 16 are 160 sq ft. These are compact but well designed. NCL put more storage into Prima’s insides than on previous ships. The bed is higher than usual, leaving room for full suitcases underneath. The bathroom has a proper glass-door shower, not a curtain.

For location, aim for Deck 12 or 14 midship. These decks have a mix of inside and balcony cabins, so the corridors are wider and quieter than pure inside-cabin corridors. Avoid insides on Deck 5 aft if you are a light sleeper. That section sits close to crew areas and you may hear activity in the early hours.

The honest take: inside cabins on Norwegian Prima are tolerable. They are not coffins. The design is modern and the storage is good. But there is no virtual balcony or porthole, so you lose all sense of time without setting an alarm.

Best Suites

Norwegian Prima’s suite structure splits into two tiers. Non-Haven suites (categories SH, SI, SJ, SK, SL, M2, M4, MA) sit on Decks 9 through 16 and give you more space and a bigger balcony but no access to The Haven’s private facilities. Haven suites (categories H2 through HE) include butler service, a private restaurant, a private infinity pool, and priority everything.

The best value suite is the Club Balcony Suite (category MA) on Decks 9 through 11. At 265 to 291 sq ft with a 45 to 50 sq ft balcony, it is not dramatically bigger than a standard balcony. But the category comes with a bottle of champagne on arrival and slightly upgraded amenities. The price premium over a standard balcony is often modest - around GBP 300 to 500 ($375 to $625) per person on a seven-night sailing.

For The Haven, the entry-level Penthouse with Balcony (category HE) on Decks 12 through 15 starts at 368 sq ft. It includes all Haven perks: butler, private restaurant, infinity pool, priority boarding, and the premium drink package. The upgrade from a standard balcony to a Haven Penthouse typically costs two to three times the base fare. On a seven-night sailing, expect to pay upwards of GBP 3,500 ($4,500) per person for a Haven Penthouse.

Is the Haven worth it on Prima? More than on older NCL ships, yes. The Prima-class Haven has a significantly larger private sundeck, an infinity pool, and al fresco dining. It feels like a genuine ship-within-a-ship rather than a roped-off corridor. But it is a lot of money. If you are on the fence, buy a Vibe Beach Club pass and a spa thermal suite pass instead. You will get the quiet adult-only space for a fraction of the cost.

Best Cabins for Specific Needs

Solo Travellers

Norwegian Prima has 73 solo studio cabins (category T1) on Decks 12 and 13. At 95 sq ft, they are compact, but they include a full-size bed, a proper glass-door shower, and a small desk. No single supplement is required. Studio guests get exclusive keycard access to the Studio Lounge on Deck 12, which has free snacks, coffee, and is a good place to meet other solo travellers. I found the solo get-togethers and social events on board to be a genuine option for those who want company. For more on why cruising solo works, I have written about it separately.

Accessibility

Accessible cabins on Norwegian Prima are available across inside, ocean view, balcony, and suite categories. They are spread across multiple decks rather than clustered in one area. The accessible balcony cabins have wider doorways, roll-in showers, and lowered fixtures. Most are located close to lift lobbies. NCL’s booking system flags accessible cabins clearly, but availability goes quickly. Book early.

Families

Family Balcony cabins (category B4) on Decks 9 through 16 sleep up to four with a double sofa bed. At 231 sq ft, they are tight for four but manageable for a week. Connecting cabins are available on most decks - look for the double-ended arrow on the deck plan. For families who need more space, the Family Suite with Master Bedroom (category SJ) at 388 sq ft is on Decks 9 through 16 midship, close to lifts and to Splash Academy on Deck 15.

Couples

The aft-facing balcony cabins on Deck 9 (category B1) are the romantic pick. The 102 sq ft balcony is big enough for sunset drinks with privacy. For couples who want quiet, avoid Decks 15 and 16 midship where the Speedway noise can intrude. Deck 11 aft, in the Club Balcony Suite category (MA), gives you a quiet cabin with a balcony and a small premium feel without Haven pricing.

The Sweet Spot: Best Value Cabin

If I were booking Norwegian Prima today and wanted the best value, I would book a standard balcony cabin (category BA) on Deck 11 midship, port side, cabins 11100 through 11150. Here is why.

Deck 11 has no public spaces directly above or below. It is three decks above the theatre and entertainment areas, and well below the pool deck and Speedway. The midship position means less motion on sea days. Port side puts you away from the Ocean Boulevard promenade, which runs starboard on the lower levels.

You sacrifice proximity to The Haven’s private areas (irrelevant unless you are a Haven guest) and you are a lift ride from the pool deck. But you gain a quiet cabin, central location, and a standard fare. The BA category on Deck 11 is almost always cheaper than the same category on Decks 14 or 15, and the cabin is identical.

Cabins to Avoid

Three zones to be cautious about on Norwegian Prima. First, Deck 9 forward cabins sit directly above the Prima Theatre and Club. Late-night bass and music will travel through the floor. If you go to bed before midnight, avoid this area.

Second, cabins on Decks 15 and 16 midship can hear the Speedway racetrack on Decks 18 and 19 when balcony doors are open. The go-kart engine noise is surprisingly loud.

Third, several balcony cabins between Decks 9 and 16 have views obstructed by The Rush and The Drop dry slides. Specific cabins to avoid include 16190, 16192, 16790, 16792, 15196, 15198, 15796, and 15798. These have slide structures passing directly in front of the balcony. NCL does discount some of these as obstructed-view cabins, but they can also be noisy during the day.
