Just some observations from a Vistana owner that has been absorbing all the information regarding the Abound program which has been very helpful.
1. We purchased Vistana VOI 18 years ago because we basically liked the Starwood program and the participating resorts which we have enjoyed going to every year. Over the years, we have now stayed at 16 of the 23 resorts. We really didn't purchase with the idea of trading either through RCI or II because for us, going to Hawaii, St. Johns, Cabo, Lagunamar, Scottsdale, Vistana Villages, Westin Riverfront, etc. has been enjoyable and easy through internal trading in Vistana. If we wanted to go to Marriott resorts (which we have) we simply used Marriott Bonvoy.
2. It seems to me that trading (converting) to Club Points is something akin to trading the same horse twice. I certainly would not do it to trade back to my own resort. (or one that I could reserve internally through Vistana) It also appears to me that that when you start converting, a big wet bite is taken by Marriott. That's why I see inequity or imbalances as a result of a conversion when reserving another property.
3. Last summer (June 2021), I was successful in securing seven(7) units (an outlier to be sure) at WKORN and Nanea, three of which were ocean view and four resort view. This was a combination of of two and one bedroom units to accommodate 22 adults. I had to borrow from this year's SO to accomplish it but was well worth it for 7 days of sand and surf. I did a computation of what I would have had to pay if I rented directly through Westin and it was approximately $40,000. I did the same thing when our whole family went to the Westin St. John resort. I did it all through the Vistana internal reservation system and I did it without converting anything and it cost me nothing.
4. The point is: None of this easily happens (if at all) through the Abound program. I do know and understand that Tuggers here have found new and creative ways of converting and exchanging effectively using their owner interest. It's all interesting and fascinating, it is.
Know this however, the average timeshare owner is not as sophisticated and dedicated to spending the time and effort to trading as Tuggers.
I'm not saying that I will never convert my Vistana VOI to Club Points, I'll probably first have to get tired of going to Hawaii, Caribbean, the Yucatan, Arizona, Colorado or Harborside. I'm sure that will probably happen some day.
