My husband, a lifetime PP, and I are here on the final day of a 6 night stay. This is probably the worst Marriott stay we have ever had.
We had requested an upgrade months ago using SNAs since he has 10. We got an email saying they were unable to fill. Checked in online the day before the stay started. Booked a basic room so not expecting a great upgrade but hoping for at least a decent quiet room.
When we checked in there was no mention of his status. We got to the room, it was terrible. I am in the lobby now:

Our patio is one of the ones behind the hedge. We had also not received our breakfast coupons. Went back to the front desk and asked why we didn't get any mention of PP status and they said because he had no MR number in reservation. Of course we pointed out this was impossible since we both requested a suite night award and checked in online. They shrugged and said "we use a different system" They added his number to the reservation and gave us coupons.
They said the hotel was sold out, no better rooms.
As the lobby got louder that night I got more mad. I called the PP line. They called the hotel. The hotel offered to move us to the room directly above ours. I couldn't see packing everything up for a room that was only slightly better. Every night the lobby noise goes until about 2:00 a.m. and the kids start running around outside at about 6:00 a.m..
FYI our friend, silver, checked in same day, same rate, high floor, partial ocean view.
