We recently sailed to Bermuda from NYC on the Norwegian breakaway with our 2 children (1.5 and 4.5 years old) and in-laws. It was the first and last time we will ever sail on a Norwegian cruise.
We paid for a mini-suite with balcony and the room was tiny but we expected it, since it's a cruise. What was annoying was that my in-laws paid for a balcony room and it was the exact same size for a lot less money. Strike one.
If you're traveling with young children (under 3) there is little to nothing to do with them. The choice of activities is extremely limited and their baby playroom is a tiny room at the front of the boat with some picked-over toys and a boom box. My son wanted nothing to do with it. The Splash Academy Kids' Club is for children potty trained and over the age of 3. My daughter went 2 days and never returned, although the staff was very kind and we did like them a lot. If your kids like the pool, be careful. It's a salted pool but has so many chemicals in it that our skin was burning. My daughter, who I usually have to drag out of the water, wanted absolutely nothing to do with it because it was so incredibly salty and chemically altered. The Nickelodeon activities are embarrassingly bad and the "family party" started at 8 pm and lasted an hour. It was thrown together with last minute-type activities and like everything else for kids, was completely underwhelming.
Tiny, cramped room. Extremely challenging to live in this space with 4 people for 7 days. Very little storage space.
The water in the bathroom was extremly hot and there was no cool water option in the shower. This proved very difficult with 2 young children as the shower was too hot for them both.
Hallway was very tough to navigate with strollers or electric scooter.
Fairly easy getting on and off the boat. Check in went smoothly.
