These nuts claim they are calling on behalf of Carribean Cruise Lines offering free cruises.  These talk this up quite a bit and wet your appetite alleging all the of the fun things you can do on the cruise ship.  They claim they are offering free cruises so you can tell your friends about the Carribbean Cruises so they'll get more business.  Here's the catch people:  they want your credit card number to pay the port fees and taxes which they claim need to be paid up front before they proceed with this supposedly free offer.  Give me a break.  If it smells fishy throw it back in the pond and hang up on these fools!
