This may be your problem. Some timeshare people just plain don't like DVC -- they think the 2 BRs are too small and you're too far from your car and that DVC just isn't up to the quality of (for instance) HGVC, which is one of the ones by Seaworld. I think in terms of 1 BRs DVC does better, but I don't follow that as closely. If your MIL hangs out on timeshare boards and has heard some of the outraged TS rants I have on DVC and how it's overpriced and nasty (I sometimes suspect RCI trades may have higher odds of getting tired units), maybe that's influencing her. On second thought, it's also a challenge to get BLT through RCI right now, so maybe that's at the root of it. Most people who put in an on-going search and have some flexibility get it, but if she doesn't like committing to an on-going search her odds are not good. There are lots of RCI possibilities that are easier to get and much, much closer than Seaworld, so maybe she's sticking to what she knows (although if it's HGVC, there's one a lot closer than SeaWorld).
