Thanks for the great replies.
When we bought, we lived in San Diego and we were visiting WDW for 10-14 days every year. Now that we live in Tampa, we've OD'd (Over Disneyed).
When we tried to do an II exchange, we found that all of our choices (any Caribbean and Australia) were not available. We've been looking at Hyatt and Marriott as an alternative and thought that this may be a good time to move on.
Years ago I tried renting points, but didn't have much luck so I hadn't considered it. Now that I'm back on the boards, I see that it's almost become an industry. Maybe we'll go that route instead of selling. Less chance for the inevitable seller's remorse.
Thanks again for the advice. I would've never thought of TUG as a marketplace.
