nearly all of SA's lodgings are excess time share rooms.....most of their "Service fee" is the resort's weekly maintenance fees.
I've been very successful several times in the past with a few airfares as well as the occasional room in Costa Rica/Venezuela/Ecuador/Mexico - helps to know the properties...AND the going rate...(find a friend who owns an RCI share and look at the books) be patient if you bid. Know the market, SA always has another right behind the one you are bidding on.
That said, looks like our orig poster got heself a deal! go enjoy!!!!!!!!!!
