I've only been on Carnival Cruise Line ships, but I found them to be amazing.
I would recomment Carnival Cruises, they have many different ships and cruise to many parts of the Caribbean, they are known as the "fun ships" and you can have a great cruise with them.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
