It is irrelevant. If there are 0 people in the world willing to stay in the Bungalows, then the (about) 1,000,000 points that constitute the bungalows will be sold to people planning on using them for the studios.
Numbers are approximate:
Poly Studios - total 3 million points
Bungalows - 1 million points
Total 4 million points.
If NOONE buys points with the intention of using them in the Bungalows, Disney would declare total victory! That would mean they sell 4 million points, for 3 million points worth of studios, which means 1 million points going into breakage every year, then Disney rents out the Bungalows for cash,
DVC-Poly members pay for their upkeep. That would be pure profit for disney, as Poly-DVC members would basically have paid for the construction of the Bungalows, and then handed them right back to Disney. They(Poly DVC people)did not finance the construction of the Bungalows, they outright paid for it!
Now of course, DVC people will stay in the Bungalows, so the above is the extreme case, but from Disney's perspective, they would love it if no dvc member ever stayed in them! From a business point of view, those bungalows are BRILLIANT!
