My 5 star review is based on the entire experience. Obviously not everything was perfect. Nothing is. This was our 7th cruise, 6th on NCL.
The great - Brand new ship that is beautifully appointed. Art work was wonderful and the ship was spotless. New features include. More USB ports in room (no power strip needed) Bathroom had plenty of storage space. Interactive TVs throughout ship to book shows, restaurants, etc. (although you should really book your shows and specialty dining 90 days out on the website.) Immediately after boarding you should go to the designated area and finalize your bookings for things you are unable to book online, such as comedy shows and race track.
Service and staff - overall were outstanding.
