I am just staring out and I am really excited. We were approved for the United Mileage Plus card. I did a lot of research and I felt like this was the best card for us. I have two questions. 1. should I also get a Marriot CC? my husband has a Marriot rewards number. If I can use my United points for hotels then what is the benefit of getting a Marriot CC? 2. do I have to wait until the next billing cycle to pay off the United CC in order to get the points credited? Or can I charge the card and pay it off in the same billing cycle and still benefit? thanks !
