Got it. Right now, I've only got 164k points. I'd be reluctant to transfer more lucrative credit card points in for "junk night" Marriott redemptions, but I certainly see your point. Thank you for your input.
As an aside, I completely forgot to check that option before booking my flight. Thanks for the reminder for future trips.
