My wife took a Delta bump for a $1500 gift card. We have a November Mexico City trip, so I thought the Marriott card would be great. Then I read it can't be used to prepay a reservation (??) so I took the Amex card. They sent two, $1000 & $500. Apparently there in no way to prepay with two cards. I did the math to split the reservation but the results either leaves me owing $48 more than the card has or leaves me with a $250 on the card which isn't enough to pay for another night. I can't wait until I get there as the cards expire in July. I've called in and emailed both Marriott and the hotel without success. I would never have believed it could be so difficult to give a business $1500.00.
