The Cabins debacle (and by extension the "Reflectionization" of the campground) shows how tone deaf current WDW management is and underscores the complete lack of understanding they have in their own products and customer base.
If sales are indeed poor, a sizable portion of your traditional DVC customers, who prefer amenities and convenience, aren't buying in because of the perceived lack of amenities and convenience.
And a large portion of Ft. Wilderness "cabin" fans (like our family who loved the property and made multiple week-long visits each year for more than a decade), are completely turned off because the entire theme and much of what we loved about the place has been stripped away.
I'm not sure the first subset of guests could be won over by this project no matter what direction it took.
But WDW had a golden opportunity to convert a ton of cabin fans to happy DVC customers if they had just kept the theme of the cabins and campground intact.
Heck, I've always been super wary of DVC but would have signed up in a heartbeat if they'd just updated the existing cabins (or replaced them with newer versions of the same).
Ft. Wilderness isn't for everyone, but those who do like it are pretty passionate about it.
Maybe Disney has data to back up its decision, but building something that manages to alienate both sets of potential customers is certainly a head-scratcher.
