Nobody can say for sure. I wouldn't apply for two at once. Apply for the CO & then the Marriott about 60 days later. If you are denied the Marr. card you can call & tell them why you REALLY need it. Everyone's situation is different but I was able to convince them I NEEDED the Pref. Sapphire card with little effort.
With Chase you have a better chance of success if you wait 60+ days between apps. in my experience. But too many TOTAL hard pulls can disqualify you too.
