First, Everyone has the rite to their opinion of a ship and cruise line. Just because you have been on NCL and liked it does not mean everybody else will. I have been on NCL and thought it is the very bottom of the barrel of the cruise Industry. Bad service, bad customer service, bad food and bad ship lay out.
Second. I'm sure it was not a "Concentration Camp" I know NCL is bad but it is not a "Concentration Camp", that description can offend people who lost family in a real Camp.
Third, give specific examples of why it was bad. For the cabin door issue did you call the desk and ask them to look at it ? At the port, what do you mean "Racial disadvantage" What did they mess up so bad at the port that you had to be escorted off the ship ?
Did you stop and think there is a reason the price is so low on certain NCL ships....... like that is the only way they can fill them up ?
