changing names in the future is not difficult (or at least i hope not)
what about folks who are trying to sell what they have now though? that is the sticking point we have.
i dont think putting all vistana points listings, nor marriott points listings under the name "abound by marriott vacations" would do anything more than cause a TON of emails sent to us when folks try to post listings!
But all Marriott-branded pure-points ownerships ARE Abound by Marriott Vacations ownerships! If someone is selling Marriott points, they're selling Abound Trust Points.
I might be confused in thinking that you were trying to distinguish among points systems? That's why I first mentioned that I'd change from your MVCI label to the Abound label, because MVCI generally refers to the Marriott-branded Weeks that come under the MVW umbrella. I didn't mean that the three Vistana points-based options shouldn't also be in your list.
But if you're also looking at Weeks-based ads, Marriott Weeks should still be listed as "MVCI / Resort / Season / Unit Size / Unit View (or whatever is the typical ad info.) It doesn't matter with ANY of these if a current owner has enrolled the Week in the Abound Exchange Company because the enrollment doesn't transfer to the new owner and upon resale the Week becomes ineligible for enrollment by the new owner.
With MOST Vistana Weeks, the same thing applies - enrollment ceases upon transfer and the Week becomes ineligible for enrollment by the new owner. But as I've been corrected, apparently there are select Vistana intervals for which enrollment does transfer - in those cases the resale would still be of the underlying Vistana Week/Points and not a resale of the Abound Exchange Points for which the interval can be elected. So, the ad would be listed as "Vistana / Resort / etc" or "Vistana / Flex / etc" or "Vistana / Adventuras / etc." (and possibly there could be space for the Seller to note that Abound Exchange Company eligibility transfers with the sale?)
Trying to boil all this down to the most basic, does it help to know that there are ZERO Marriott or Vistana or any other ownerships for which an owner has elected a permanent exchange of an existing ownership to Abound Trust Points? It can't happen. That's why only people who have purchased Abound Trust Points can be selling an Abound points-based membership that comes under the Marriott umbrella, and why everybody who is selling any intervals that are eligible for Abound Exchange Points elections is selling the underlying ownerships and not the Abound Exchange Points for which the Sellers are eligible. Marriott, Vistana, the brand doesn't matter. No intervals can be permanently exchanged for Abound Exchange Points, and Abound Exchange Points are not something that can be sold. (Rented, yes, but not sold.)
