I have always added my Marriott Bonvoy number to my Interval reservations. A long time ago, I would call. But, for many years I have used marriott.com and simply added or changed the bonvoy number. However, with my latest Interval reservation, when I try to add my bonvoy number to the reservation on marriott.com, I get an error code (after many tries). I believe I saw another post (I think by Jeremy) mentioning the same thing. My ultimate question is whether anyone has figured out how to add the bonvoy number to Interval reservations now? I strongly prefer to put the number on in advance because I can then see the reservation in my bonvoy account and on the app. I've also had trouble getting the number added and staying added at the resort. Finally, I've been told no credit for interval stays after the fact when the bonvoy number was not on the folio (even though added at the resort).
So, any thoughts on how to get the bonvoy number added now?
