thank you very much for your reply.
I have already analyzed their web sites and also Clia,Ecc Reports and so on.
But unfurtunatly i didn't find specifical information about luxury cruise market (trends, growt, data)

now i'm also very interested in how these companies have changed/are changing their communication and marketing strategies in order to stop "Concordia Effect" (if they was affected!).
do you have some ideas about it? Maybe as far as prices/discounts are concerned? or maybe their are focuses their attention on different topics (such as safety and security)?

thank you?
