Why not swap it with somewhere else? That is the whole point of Timeshare. Our was 30 mins from us, so we always swapped it all over the world. We bought the weeks because we could use the facilities (pool, sauna, steam, jacuzzi, tennis, squash, billiards, pitch and put, gym, etc) year round.
You can also exchange with 'Dial an Exchange' - much cheaper, and you can swap a 1 bed or 2 bed, for a much larger unit, for same price. With RCI, you can also swap for cruises too.
Why not advertise it in your local paper? Be prepared to sell at very reasonable price though. Is it on a Lease (how many years left) or in perpetuity?
