My stays are constantly posting wrong.
In most cases I don't get the 1000 platinum gift points / any other extra point (from special rates), for which I always try to call the hotel, that blames Marriott, then Marriott, that blames the hotel, until 10 days pass and then they can credit them manually.
I've NEVER had such problems with 4 years of loyalty to SPG, despite having had complex bookings.
