And no, Marriott call center associates cannot, nor can properties, reduce the point cost of a night. No matter how much you complain, ask for managers, no one can change the cost of the nights. It's done by a computer. The people that can change those things are in India...and no one can get them on the phone. So, save yourself the time and frustration, re-run the rates OUTSIDE of your reservation, see if it's a change you're willing to accept, if so, then actually do it. Otherwise...it is what it is.
