My 80 plus year old Dad is taking my stepmother to Hawaii in Dec 2012 and they have booked at the Hilton to be near her children/grandchildren. He has asked my advice about getting a new credit card to help pay for his rooms. I can only find 2 cards (AE and citibank) offers. I was hoping some of you experts could offer me advice to help him out. Thanks in advance from she who watches.
