I have to disagree. We are in our 70s and spent three nights on the Carnival Fantasy from Port Canaveral. Maybe we were lucky but it was one of the most enjoyable cruises. The younger crowd showed us nothing but respect, holding doors for us and asking us to get in front of them. We even danced our slow dance in the back of one of the clubs while most others danced the new way in front, and nobody cared. Of course Disney is the best (we've cruised Disney three times) if you have children or grandchildren, but you have to be able to afford it. It's by far the most expensive.
