Thanks for the great advice Neil.
I agree about not opening unsolicited emails and offers. Seamiles has my email because I have the notice turned on for statement notices in case I lose one in the mail. I know who Seamiles is, because I pay the bill every month.
LHP, I had the original Carnival Card too. When they changed banks and the program details, it went south for me. I had almost enough points for the free 3 day, and then they were converted to worthless discounts.
