I got Sheraton Broadway Plantation 7/4-7/11 2br from SFX for this summer.
Probably could have gotten the same week with II, with my Lakeside Terrace week(*wood preference).
Would I deposit another week with them, probably not. I don't like sitting and waiting for the call, can't check on line avail. like the Big 2. I know some people think they play favorites with a few customers and/or resorts.
Now I have talked to Elena and Mark at SFX, they do get back to you promptly and answer questions with realistic answers(don't blow smoke up your bum about the chance of getting a certain exchange).
I think most of their deposits come from hard core TS'ers like us Tuggers. I think the average person just goes with II or RCI to deposit their weeks. So the volume isn't there.
