I have posted this before elsewhere in other threads. We own Westin Flex and Sheraton Flex, both developer purchases, and both purchased prior to August 2022. We could see both ownerships in our account before the updated Vistana dashboard was rolled out. After the rollout, we could only see the Westin Flex VOI information. We had to create a second, new Vistana login in order to see and access the Sheraton Flex VOI information. During an owner update at Nanea in early February 2023 the rep we were with said this multiple login issue is a major complaint they hear from other owners. His explanation was that MVW is treating the ownerships as 5 separate entities: MVC, SVC, WVC, GRM (Grand Residences by Marriott), and R-CC (The Ritz-Carlton Club). He said there is no plan to be able to merge these under one ownership access portal. When any of these ownerships are converted into club points, then you can see the converted club points in Abound. On a webpage he went to that is the currency converter to Abound, was a drop-down that required you to pick from one of the 5 ownership types above. I’m not sure if that calculator is accessible by any of us owners as I have not found it on my own.
When we converted both VOI’s to Abound club points in late February, we could see both ownerships at their converted club point values listed separately on the Vistana/Abound/MVC portal (e.g. the stripped down MVC website that we Vistana owners get sent to when we select to use our club points from the Vistana Dashboard).
This explanation still makes no real sense to me, but I am relaying what we were told.
