Cruise commercials. Empty shells?

Cruising is a wonderful experience and a whole lot easier and less expensive than other vacations. So why is it that cruise lines can't seem to up with truly appealing commercials?  I don't know about you, but I think this "The sea is calling" is a really stupid concept, though not nearly as stupid as their previous misconception, "The Nation of Why Not." Okay, so you see a lot of desperate for escape people on city streets joyously holding up mysteriously appealing conch shells to their ear. Wowie. How about showing us a ship, an island, a munificent buffet, a spa, or a spacious stateroom with a balcony? Do they really think a conch shell, which you pick up at any island souvenir shop is the ideal image for their product?  Give me a break. The amazing thing is the other cruise lines aren't much better. Celebrity has done some good spots in the past. Carnival in recent years has really dropped the ball my making their cruises look like a wet and colorful nightmare of screaming children. I know from personal experience that powerful non-creatives at the Miami agency were convinced the were wiser than their creative team and quickly lost the multi-million dollar account with their lousy concepts.  NCL has done some nice recent commercials (though not as brilliant as their print material) pushing Cruising Norwegian Style. Although I personally don't relate superior cruising to Norwegians other than war-like Vikings so this analogy is lost on me. I still think the best commercial of its type was the first one with Kathie Lee doing a full sing of Ain't We Got Fun (or We've Got the Fun). In 30-seconds it musically showed you a Carnival ship: all the fun you can expect; attractive, relaxed and involved passengers; and reminded you of how affordable the experience was. Brilliant! Who came up with this commercial?
