Free bahamas cruise for two a scam?

Barnum was right.. there really IS a SUCKER BORN EVERY MINUTE. If you look at your FREE TRIP closely, and compare it to booking a the trip of your choice through the internet, you will find out that your FREE TRIP will COST YOU MORE than if you just book the trip you want on the ship you want... Cruise ships companies keep putting out these FREE TRIPS and GULLIBLE people keep biting on it because Amerikans are GREEDY and want SOMETHING FOR NOTHING
