I agree with you Norm, there the cruise lines vary just as people's taste vary. So a casual cruiser would be comfort on NCL just as a cruiser who likes to dress up would be more comfortable on Celebrity. The problem arises when the TA or the person booking doesn't understand Cruise lines differences and puts a casual cruiser on a formal line. I'm in between Celebrity is to formal and NCL is too causal. Carnival is just right for me I like jeans and formal night.
