We were 3 girlfriends traveling together, ages 27, 35, and 35.
We had a great time with each other because we had the mentality that we were on vacation, there to have fun and to enjoy each other's company. Because of that and NOT b/c of the services offered by Norwegian, we had a good time.
That said, I would not sail on this ship again. Here are the details:
Pullout sofa blocks walking path from other beds to the bathroom. Only 1 electrical outlet caused problems for 3 girls. Terribly flat pillows.
