So for my Friday reservation, the hotel sent me a standard pre-arrival, and I responded back with respect to a Fedex delivery and mentioned that the SNA had not yet cleared (with no request that they do anything). The hotel responded back, noted that they could see no record of the request in their system, and advised that I contact Marriott/SPG customer care, given they can't directly pull the SNAs. Called customer service, they indicated it was fine on their side, but they sent some sort of message to the hotel to advise them on how to process. The property has a pretty good record on SNAs, so to be honest I trust them a lot more than the information that corporate is dealing with at this point.
The last SNA sweep on this one is at 2pm tomorrow... will see what happens. If I had any idea that they would have done such a terrible job on this integration, I would have tried and redeem these earlier in the year. Total disappointment.
