The U.S. Marriott Resales department in Florida does not list Aruba weeks, but we know from reported experiences that the Marriott sales office in Aruba does offer Aruba weeks for sale as an alternative to buying trust points. I'm not sure where they get these weeks - whether they are all from foreclosures, ROFR, and deed-backs, or whether some are weeks that have been bought back from owners. I guess if foreclosures, ROFR, and deed-backs provided them adequate inventory to meet their weeks sales needs in Aruba, then buybacks wouldn't be necessary. Maybe some of our international/Aruba owner TUGgers can offer more insight.
Other than that, I agree with TXTortoise, if Marriott won't buy it, list it with an independent broker. In that case you name/email is known only to the broker and you won't be subject to the calls from scammers. The independent brokers sell for considerably less than Marriott, but their commission is generally much less as well. This recent linked thread mentions some reputable brokers and just doing a forum search for resale brokers should yield contact info.

Some brokers that typically get high marks here are Seth Nock/Samuel Rodriguez with Selling Timeshares, Judi Kozlowski with ReMax, Syed Sarmad with Advantage Vacations, Magical Realty/David Cortese, Conceirge Realty, and many more. I've bought a week from Samuel and one from Judi's team. I've also talked extensively with Syed, but he didn't have what I was looking for at the time.
