The reason I am "interested" in Tortola..... it is a NEW island to "discover." That is the reason I am interested it it. I LOVE "discovering" new islands.
As for NCL, you mentioned the "free styling", THAT is what most people DID NOT
like, at least that was the talk when leaving the ship, and on our flight back home. Lots of people talking about it.
As for Carnival, I "discovered" it last year. We went on the Triumph, and had a "wonderful" time.
