I have 2 Bonnet Creek and 2 Ocean Walk stays booked already for this year. One of the Bonnet Creek stays I have a 1-BR booked (was hoping for a 2-BR upgrade), but the only unit available for the dates now is a 3-BR, which I don't need and at 50% off is more in total than the 1-BR I got booked at 35% off. The other Bonnet Creek is after the 11/2 "travel by" date. The one Ocean Walk I have booked a 1-BR and got a 2-BR upgrade already. There's no current availability of a 2-BR right now for those dates, so I would risk losing my 2-BR upgrade to save 13,125 points. The other Ocean Walk I have booked a 1-BR and already got a 2-BR upgrade. I COULD get an immediate upgrade to a 2-BR unit if I booked that stay again, but I don't have enough points left this year without having to borrow points, plus I don't have any housekeeping credits left. In order to avoid having to borrow points and pay for a housekeeping, I would have to cancel the reservation I already have, then rebook it. I'd run the risk of losing it between cancelling and re-booking, plus it's only a 3-night stay, so I'd be risking it to only save 5,850 points, so I don't think it's worth it. Plus, I have relatives visiting that I promised a beach-front property stay, and I'd hate to have to tell them I lost it trying to save 5,850 points. Oh well, was fun to try. It's a good sale if it works for you!!
