Hi Greenpeacedave
Why not try with the fixed week route, Sunterra will send you a list of resorts to choose from, I think it includes Sunset Bay and you are not committed at this stage. If there is none that take your fancy, try the ebay route, you can list your points and set a "buy it now" (with escrow imp) and set a minimum purchase price and see how you get on
Take care and good luck
