I just responded to your other thread in the Family Cruising section. To avoid confusion we like to keep only one thread open on a topic. So I will close this thread and we can continue in the Family Cruising section here.
To quickly answer your concern about Carnival being on a party ship; that is a misnomer. Carnival carries more Senior citizens than any cruise line. The party label comes from the 70's when Carnival marketed to that target. They have tried for years to shed that image. They are very much a family oriented cruise line. Will you see people partying? I'm sure, as you will on Royal Caribbean.
