We had three stays at Vistana Villages over the past year. All stays were via accommodation certificates. We own in Bella and Key West (i.e. StarOptions) at Vistana Villages. In each of the stays, we initially did not receive credit for the nights stay. Our Bonvoy number was attached to the reservation and we indicated that we were owners during each visit.
The first time, I submitted a missing stay request and received credit via that request. The second stay, I submitted a missing stay request and did not initially receive credit. However, I called customer service and the rep gave me credit since I was an owner at Vistana Villages. The third stay which was in December, I once again did not receive credit via the missing stay request. When I called, the rep said that I was not eligible for credit via the "promotional rate" from Interval. When I brought up that I was an owner, the rep told me that I would only get credit for the stay if it was using my ownership and that I had to go through Vistana to get credit in that case.
Each time we stay, it is getting more difficult to get credit.
