Yep, it's the same in the MVC world. People who own in places like the off-beach resorts in Hilton Head; Doral in Florida: Branson, Missouri; Fairway Villas, NJ; Williamsburg; many of the Orlando properties; and almost everyone who owns off-season weeks can find better value trading in Interval, because their low point allocations mean they have to use multiple weeks to get one week in a high demand area. Nevertheless, when you look at Points availability for many of these places, it would seem that a lot of people are still choosing to elect for points despite the low allocations. I doubt all of the availability is due just to Trust ownership. They just adapt and bank/borrow to go where they want to, albeit less frequently. It's easy to do because there is no need to pre-pay maintenance fees and no fees to bank/borrow. At the same time, others still choose to use Interval for better value. Both systems coexist.
But it's also important to note, that many (most?) owners aren't quite as focused on squeezing the last penny of value out of every trade/points transaction as many here are on TUG. As an example, back in the early 2000s through 2013, when we owned at Kaanapali Beach Club (Sunterra, then Diamond) we would trade our Hawaii week for Orlando since we had younger kids - a terrible trade for a numbers cruncher, but it worked for us because we could just go onto RCI and book from instant exchange inventory at HGVC in Orlando without putting in one of the frustrating "request and wait" ongoing searches that we hate.
While it's certainly true that a VSN owner at a location that Abound valued lower can do better using VSN if they want to travel somewhere where VSN has resorts, it will be interesting to see the appeal that Abound may have in offering so many new places to go. VSN can't get them to Aruba, St. Kitts, Marco Island, Hilton Head Island, the Palm Beaches, Newport Coast, Las Vegas, ocean front in Myrtle Beach, Park City, Lake Tahoe, Big Island, or Oahu. VSN also can't get them to the Pulse locations in New York, Boston, Washington, San Francisco, San Diego, or South Beach, where short stays are popular and can work for folks with smaller allocations. Banking/borrowing might be required for a lower point valued owner to travel to some of the higher point locations, but it will happen. Both programs will co-exist, but over time, the balance will be determined by the choices owners make.
