I just have to say, no one can beat Carnival, I just traveled on Norwegian and it was horrible!! The ship was new and Hawaii is great, but no one can come close to the party that Carnival puts on!!!
We did Hawaii on Royal Caribbean and were equally sorry....they didn't provide us with enough to do during our many days at sea. I'm not saying that it was a horrible cruise...just that I'm married to someone who needs to be doing something most of the time. There were times on RC where even if we did go to a schedule event it was so crowded everyone couldn't fit in the room they were using...I have yet to understand why they didn't use their main auditorium more. We enjoy the choice Carnival gives us....
stay busy or lounge around!
