I agree about them being worthless for resale purposes but they have worth as traders, at least for us.
We have owned a silver and a bronze week at the Barony on HHI for a decade. We bought them with the trip around the world offer, plus additional points since we couldn't use one week the year of purchase, and free II. We have never, ever actually used them in their seasons and have always successfully traded them, including back into HHI when we wanted to, at the end of August or early September. In 2012, the Bronze will take us to the Marriott in Myrtle Beach in October, and the silver will give us a summer week in Aruba to go along with the gold week we already own. Last year we traded the bronze for a week at the Grand Ocean at the end of February (much warmer than Wisconsin), and the silver for a late June week at the Marriott Ocean Club in Maui.
We will be using getaways when we retire to add on to the four weeks we already own.
