I've done my searches here on Flyertalk, but it seems as if everyone's circumstances are different so here's my plea.

We want to head to the Caribbean, we're looking at October. We're in our late-20s. We love to eat and enjoy a glass of wine with dinner. We're looking for a line where the cruisers trend younger, but where we won't be driven crazy because of large numbers of screaming children. We're looking at a Miami, Ft. Lauderdale or Port Canaveral sailings. 4-7 nights.

I was leaning towards Norwegian, but Carnival, Celebrity, Royal and Holland all look alright too.

Thanks for any help!
