Hi everyone,

I am struggling to find a concrete answer for this one... I am a platinum member at marriott, staying at marriott 4 days per week every week at a rate of $115 per night. I also fly delta, with gold status. What is better bang for my buck, doing the 3x delta miles promotion or sticking with marriott points given my platinum bonus.

With your answer, can you please / hopefully provide the math / logic. Thank you for your help!
