Interesting responses from all of you. The last comment about going on cruises only for the ports of call though just is opposite from most of us... If I was cruising just to get to be at those carribean Islands , then I'd book a trip without the cruise part and would fly to the actual resort... Sounds like you and hubby should consider this instead of cruises.
But I liked some of the other ideas , day on , day off... day on , day off.... etc...
Hopefully carnival will read this post..
