Does anyone know how to get Marriott Swan reservation to CORRECTLY link to MDE?

My family of 4 has booked a stay through Marriott Bonvoy (using points) at Disney Swan. I’ve tried using our confirmation number to link our reservation in MDE, but only 1 member of our 4 person party is showing up for linking.

I have triple checked the reservation. It is for 4 people, not 1 person.

I have tried using the virtual chat to fix it. This has gone nowhere. I get told it should be “fixed soon” but nothing happens.

I have downloaded the Disney Sean/Dolphin app and texted with the hotel to get it fixed. This has not worked. I have tried calling the hotel directly - I just get stuck in an endless AI loop that doesn’t connect me with a human that will fix the problem.

I have talked to customer service reps at Marriott. Still not fixed.

My lightening lane window is supposed to open on five days and I am beyond frustrated that I might not be able to book because I cannot find a way to get this fixed.

Has anyone else had this issue? What did you do to actually get it resolved???
