We cruise once or twice a year usually on Princess or Carnival, the reason we decided to go on Norwegian is because we wanted to try out a new ship and since Bliss is a brand new ship it made our decision very easy.
Embarkation:
We were traveling with two children 3 and 11 months so we had a stroller. Bliss only has 16 elevators on average about 10 elevators less then any other ship we've been on with less passengers so to get on and off the ship or between the floors every-time took very long time and was very frustrating.
