I've thought about this, as well. I'm very sure they won't use "Norwegian Star" - that would be a waste of valuable resources, as they urgently need a large (and fast) ship in the Caribbean. Also, the "Star's" speed would be useless in Hawaii without calling at Fanning Island.
I agree with you, nothing seems to be impossible now.
Let's remember this is not the first cruise line planning to return the Big U to service - but it's the first line that has the capability of doing so.
I still cannot believe it - it simply sounds too good to be true!
