Thanks for the post, Marty. Although this relatively new product was discussed on the old BBS, I think this is the first post about it here.
It appears that everything, including coverage and pricing, that one needs to make a decision about this timeshare travel insurance is on the site. Start with
this page. Place your browser's pointer on the question marks for details. Click on the link at the bottom of the page for the entire plain-English policy terms.
Note that normal travel insurance policy exclusions apply - such as many pre-existing conditions. However, the pre-existing condition exception applies only in the first year of insurance, assuming one renews each year.
Also note that, unlike some RCI travel insurance offerings last year, the coverage will not be effective for timeshare cancellations caused by an event (e.g., a hurricane) that has already occurred.
Further, the coverage appears limited to owner-occupied trips, thus excluding exchanges. There is a reference to an "Exchange Fee", which is defined as the fee (if any) that you might pay to your resort's management company for rescheduling the canceled trip.
Lastly, if you own more than one timeshare, the coverage isn't available for a single trip. You must purchase coverage for all of your timeshares. However, if you own five or more weeks (or more than 31 days), you aren't eligible for the coverage!
