It’s because
direct DVC is frequently upside down mathematically! Especially if you stay in 1 bedrooms basically ever, or if you finance, or stay at low value times of year (e.g. summer), or let points expire, or rent points out, or would have been just as happy at a moderate or in a family suite, or are buying at CFW.
It’s turning into the
Disney Dining Plan where you have to do it just right to actually save money after accounting for all the things an accountant would tell you to account for. It was a much better deal prior to ~2013.
I have mentioned this before but I calculated the breakeven for SSR, worst case scenario, at ~$88 per point. IOW that’s the price where no matter how stupidly I use it and no matter how deep Disney’s discounts get, I’ll still save at least a little bit of money, assuming I use all the points. I got my contract for slightly less than that. Disney wants
$205.

They want $225 for Riviera and Aulani. Yes you can absolutely find value at that price but man I don’t want to do that legwork, and if you just compare the
point charts to the cash rates and look at the breakage rates, it’s clear that many, many people aren’t getting any value at all.
