The most frustrating part of this is Marriott's unwillingness to communicate there is an issue. Not to us and not internally.
The 'Lurker' here seems to have abandoned the thread after making the knee jerk recommendations which are not the cause of the problem.
I've documented the issue and sent it to the champion email. They responded to me once and asked for additional information, which I supplied, and that was the last I heard of it.
Not only can I not seem my res, the Ambassador's cannot see them as well. I had to provide all my confirmation number for my upcoming trip for my Ambassador to be able to contact the hotels for me.
Marriott as a corporation really has just one job to do 'provide a reservation system'
