Also, the phone call to put the rewards points onto the rewards card goes more smoothly if you are calling from a phone associated with your credit card. If the credit card company has just your landline in its records, call from your landline and give them your cell phone number. Then, if you call from your cell phone while you are on vacation to put the rewards points onto the rewards card, the call will be easier. Also, you want to make that call in private, if possible. You can get the card at guest relations, but if you make the call from guest relations then anybody in the vicinity will hear you giving confidential information to the credit card company.
