While I worked for decades on Carnival Cruise Lines, I was always told that Royal Caribbean offered better vacations. Then why do they always have such tacky commercials. "Vow to Wow"?  Give me a break. That's about as bad a campaign as I've seen, although not nearly as weak as their campaign "The Nation of Why Not" from several years ago. What could be easier to promote than an all-inclusive cruise vacation? It's fun. It's a great bargain. And you have nothing but visuals of a beautiful ships and glamorous tropical islands. Yet most cruise commercials suck. And there's no excuse for it.
