I have been working on this for almost two weeks now and am really frustrated with Marriott/SPG. I had two reservations with one being less than three weeks away from now. That sent us scrambling to find an available and somewhat affordable room. We decided to stay at the same hotel at a cash rate that seemed better than anything else we found at this short notice. Had we rebooked back in October when the hotel left Marriott, we wouldn't be in this spot, but we had repeated assurances from both the hotel and Marriott that our points bookings would be honored.
Now I am having trouble just getting my points back. I booked using SPG points in the SPG system and during the merger, I was one of the people who didn't have everything transfer properly. Some phone people can't find my reservations at all. Others can but then say I need to call SPG to do anything.
This is beyond frustrating especially when the only response I get from anyone at Marriott is to be patient.
