Does anyone have multiple Marriott Visa credit cards? I have the basic signature card ($45 annual fee) and rewards account in my name. I would like to upgrade to the black card with the 50,000 points sign-up bonus. I know that I can't get the bonus if I allready have a card in my name, however, can I have my husband apply for the card? Also, could he attach it to my Marriott rewards number/account or does he have to have a seperate rewards account?
