Just got the call on my cell phone. These cruise offers are fake. The get your personal information and you wind up with identity theft. If they answer you can listen to their pitch then say 'no thanks.'
I have had offers with real estate sales and cruises also. Come get two free tickets they say and it is really a tour of a golf course and subdivision and the tickets are usually for someplace you do not want to go or you have to pay surcharges and fees.
