I contacted Marriott via the 'Request Information' part of the site I linked. I was contacted and talked to them about a specific week, but it didn't end up being right for me. We talked about my other ownerships with Marriott, and why I was considering that week. The rep I spoke with said adding more points would be my best way to go, and I didn't disagree. I was then recently contacted by another rep (the particular rep probably isn't important) and they offered me this.
What I thought might work for you is a week in St. Kitts that is enrolled in the points program and is priced very low. First year occupancy is 2019. Maintenance fees for the week are $1,898.
Here are some examples of the purchase prices for the week, and the points they offer (prices do not include closing costs):
2,150 points for $15,100 or
2,400 points for $17,800 or
2,525 points for $19,100 or
2,775 points for $21,600
I do not know if they truly have 4 different weeks that were enrolled, or if they have 1 or 2 weeks and are willing to sell 4 of the 5 different view/villa combos available at St. Kitts. Maybe that resort was never "sold out", I have no idea. Either way, as you can see from the offer in the email, this is a week they are offering me, that is enrolled, and I would have the use of those points. They offered this to me because of the 'situation' that I described to them and the resort I would like to visit regularly, since we moved to NC. I hope that helps.
