I'm supposed to be fairly computer literate but I'm at a complete loss as to how to do this online. I have made a reservation. I see the general instructions under Marriott Rewards about upgrading with points. It tells me to look in the room description for details.
I have searched high and low all over the reservation, room details, tried cancelling and starting over, tried changing the existing reservation, anything I can think of. I see nothing in the reservation whatsoever to allow me to request a points upgrade.
So how do I do it? Where did you hide the "Upgrade with points" button.
The specific hotel is the JWM in Bangkok Thailand.
