On my first timeshare, the Sands of Kahana, the EOY ebay listing showed the MF at twice the amount that it should have been. I knew what the correct MF should be, but that error in the listing resulted in essentially no one else bidding. I thought that since it was an EOY that they made a simple mistake. After I won the bid and things were progressing, I think that the seller or closer requested an estoppel because I was contacted that they had actually sold me TWO WEEKS EOY. The seller said that I could either accept it at the bid price, or I could back out. The seller said that the cost to split the week into two weeks and resell would be significant. So, I ended up with 2 weeks EOY. For me, that is great. An unexpected benefit. After all, with the expense of flying and losing a day in re-acclimating, staying 2 weeks makes more sense than staying just a single week.
