They will need more inventory once they schlep off the rest of animal kingdom...as the only thing we KNOW about disney construction is that they will have something in orlando that's new to sell - hell or hurricane high water.
It wouldn't appear that they would have difficulty selling the grand floridian out quickly...it has a natural draw for those seeking luxury (which they don't provide at the "grand" or any other disney run property - but that's another story) and it is small by the recent standards - 300 at contemp, 450 at animal kingdon, 1.2 billion at saratoga.
So they will need to move sooner than later to get something started.
But the buffalo junction thing would be a curious move in several ways. ft wilderness and wilderness lodge are great...but kinda sleepy. In order to build 200-400 dvc units they may also have to inject more in the way of services into the immediate area to accomodate...and they have been rather hesitant to do that with DVC construction when possible.
But if that's what they're saying....that they can maximize/ exploit the work in MK, the contemporary, and use the facilities more at Ft. Wilderness by plopping more units on the lake...then go right ahead.
However, it would seem that an "expansion" of the wilderness lodge unit - even if it's a half mile away - would be a better tact than builidng a new standalone plopped right next to an existing, smaller unit.
but my stance on this still holds: mark out the lagoon at the polynesian...its inevitable and a hot sell.
perhaps...knowing that it would be a slam dunk at the poly...they are attempting to go "every other" when it comes to high profile DVC construciton....build at contemporary, take more of a risk at animal kingdom, build at grand floridian, try to flesh out the ft wilderness area, THEN build another at contemp or at poly...
And animal kingdom hasn't seen the last of DVC in its area as well. that park underperforms and costs a fortune to run...they will put more DVC near it before too long to try to entice more traffic into the park - count on it.
