To a certain extent, it may actually be better for Disney. If people knew they would get a 2nd/3rd floor view, some will certainly consider it worth owning a fixed week.
Similarly, if they introduced a true standard view (parking lot view) for lower points, it likely increases demand. As evidence, look at AKV, BWV, and BLT standard view popularity. People complain that they have to book in early September and walk their reservation if they want late October.
OKW HH, BWV standard view and boardwalk view, AKV Concierge and standard view, etc are all examples where it makes owning more important because there is limited supply for high demand.
It does mean there may be slighly more openings (night here/there).
However, I'm in the category that believe limited supply helps Disney enough that it would be a wise decision.
Oddly enough, PVB may be the most extreme treatment of point options. Say it's 4 million points, only 3 room categories. BLT is just under 6 million points for 14 booking options (studio, 1BR, 2BR LO, 2BR Ded) standard, lake, theme park view...plus GV lake and GV theme park. VGF is even more extreme...about 2.5 million points for 10 booking options (studio, 1BR, 2BR LO, 2BR Ded) standard view, lake view plus the GVs.
I guess the question is whether spreading the points around to more booking options hurt the other resorts? I see why people think it's better to have fewer categories, but it would also be better to sell only a week's vacation like other timeshares. Much easier on the system if you only sell fixed weeks. I'll take a 100 flavor ice cream shoppe over a 3 flavor ice cream shoppe any day.
