I have just returned from a transatlantic cruise on the new Norwegian Breakaway. Here is a summary of my experience and personal opinion.
First of all I made the mistake of booking direct with NCL which turned out to be a lengthy nightmare (eventually got sorted after numerous long distance phone calls) wont be doing that again , will book with a travel agency in future.
Check in at Southampton was complete chaos with the systems continually breaking down and causing lengthy queues. I would have thought there would have been some kind of welcome reception for us after all it was an inaugural voyage and believing the hype was expecting something special. But nothing , not even the welcome you get when returning to the ship from a visit to a port.
Tiny wardrobe, no drawers,. very claustrophobic. No noise but because of corridors leading off main corridor very confusing trying to negotiate the route from the lift.
