However, I did find something great on their website just now:
Member AdvisoryWe would like to remind all Festiva owners and members to take extreme caution when you are contacted by someone claiming to have a buyer for your timeshare, or who will sell it for a guaranteed amount. These solicitations typically come in the form of phone calls, e-mails or mailings of postcards or flyers.
Please note that Festiva is not affiliated with any resale company, and we never provide resale companies with any personal information about our owners and members. If you are contacted by any company other than Festiva, particularly if they claim to be affiliated with Festiva, please contact Member Services immediately at 866-933-7848 or email@example.com with as much information as possible about the company or individual who contacted you.
For more information about timeshare resales including consumer advisories, please visit the American Resort Development Association's Resale Guidelines or the ARDA-ROC Timeshare Resale Resource Center.
I do wish other resorts would post these advisories...
