Is the list of resorts approved for
DVC trades still online? I just looked for it, and couldn't find it.
I'm not sure where the Smokey Mountains Westgate is located, but I know that Foxrun in Lake Lure NC is on the DVC-approved list, and it currently has an August 23rd week available at Interval. But, there is no way I'd ever give up 270 points for a week's stay at Foxrun, and I say this as a Foxrun owner! For what you'd get in cash for renting out 270 DVC points, you could buy a Foxrun week and have enough money left over to pay several years of annual fees there.
Mountain Loft in Gatlinburg also has some August 2008 weeks available in II, but again, you should be able to buy a week there for less than the value of 270 DVC points (and I'm not sure if it's on the DVC approved list.)
