Some opening comments
1) this was our second year taking this exact cruise aboard the Norwegian Dawn (here's last year's review http://www.cruisecritic.com/memberreviews/memberreview.cfm?EntryID=105557)
2) My friend and myself cruise for relaxation (both in our mid-30's). We don't go to explore the nightlife or drink ourselves silly. We go to enjoy the sun, read, relax and rest. So that's really what I can comment on. If you're looking for a review of all the activities - this one might not be for you!
